By the Proud Mobile Welding, LLC Team
Short answer: Call a mobile welder who offers 24/7 emergency service and can repair the bucket on site. Most cracked side cutters, broken welds, torn wear plates and loose tooth adapters can be repaired where the machine sits, often the same day. That gets you back to digging without hauling the excavator to a shop.
Key Takeaways
- Most excavator bucket damage, including cracks, broken welds, worn edges and loose adapters, can be repaired on site by a mobile welder.
- Stop digging as soon as you see a crack. A small crack grows fast under load and can turn a repair into a replacement.
- A proper bucket repair means removing the whole crack, preheating the steel, and welding with low-hydrogen filler metal. A bead laid over the top won’t hold.
- On-site repair usually costs less in downtime than hauling the machine to a shop, because the excavator never leaves the job.
- Some damage, like a bent bucket shell or badly worn pin bores, may call for more than a weld. A good welder tells you that up front.
Can a Mobile Welder Fix an Excavator Bucket On Site?
Yes. Most bucket repairs are field work, and that’s the point of mobile welding. We bring the welder, generator, gouging equipment, preheat torches and wear parts to the machine, so you don’t lose a day loading it on a trailer.
We see the same damage over and over on the job:
- Cracked side cutters and side plates. The corners of the bucket take a beating when you’re prying rock or roots.
- Broken or cracked welds where the side plates meet the bucket shell, or around the hinge and link ears.
- Worn or torn wear plates and wear strips on the bottom (the heel) of the bucket.
- Loose, broken or worn tooth adapters. An adapter is the steel nose welded to the cutting edge that the teeth slide onto.
- Worn cutting edges that are too thin to dig efficiently.
All of these are standard on-site repairs for us.
What Should I Do Before the Welder Arrives?
Stop using the bucket and make the machine safe. Every minute you keep digging on a crack makes it longer and makes the repair bigger.
- Park the machine on level ground and set the bucket flat on the ground or on blocking.
- Shut it down and relieve hydraulic pressure per your operator’s manual. Follow your lockout/tagout procedure.
- Knock off the mud and packed dirt around the damaged area if you can do it safely. Clean steel saves us time.
- Take a few photos of the damage and text them when you call. That way we can bring the right wear parts and plate.
- Clear the area of anything flammable. Welding throws sparks, and dry brush, fuel cans and oily rags don’t belong nearby.
How Does an Emergency Bucket Repair Work, Step by Step?
When you call us for an emergency bucket repair, here’s what happens:
- You call and send photos. We ask what machine you’re running, where the damage is, and how the bucket is being used.
- We roll out with a fully equipped rig. The welder who talks you through it on the phone is the welder who shows up and does the work.
- We inspect the damage. We trace the crack to find where it really ends, since cracks usually run farther than they look. We also check for damage nearby.
- We remove the crack completely. We use air carbon arc gouging or grinding. Air carbon arc gouging uses an electric arc to melt the metal and compressed air to blow it out, which cuts a clean groove down to solid steel. Welding over a crack without removing it just hides the problem.
- We drill crack-stop holes at the ends of the crack when needed, so it can’t keep running.
- We preheat the steel. Bucket wear parts are often made of abrasion-resistant (AR) steel. Preheating helps keep that hard steel from cracking again next to the new weld.
- We weld with low-hydrogen filler metal, such as E7018 rod or a matching flux-core wire, in multiple passes. Low-hydrogen filler resists hydrogen cracking, a common failure in high-strength steel.
- We add reinforcement or wear protection where it makes sense, like a gusset, a new wear strip, or hardfacing. Hardfacing is a layer of extra-hard weld laid over a wear area so it lasts longer.
- We let it cool properly and inspect the finished weld before the bucket goes back to work.
Should I Repair or Replace My Excavator Bucket?
Repair it in most cases. A bucket with a sound shell, good pin bores and localized damage is almost always worth fixing. Replacement makes sense when the bucket itself is worn out, not just damaged.
| Situation | Repair on site | Consider replacing |
|---|---|---|
| Crack in a side plate, side cutter or weld seam | Yes | Only if cracks show up all over the bucket |
| Broken or loose tooth adapter | Yes, cut off and weld on a new one | No |
| Worn wear strips or heel plates | Yes, add new wear plate or hardfacing | No |
| Bucket shell worn paper-thin in many spots | Patch if it just needs to last a short time | Yes |
| Bucket bent or twisted out of shape | Rarely | Usually |
| Pin bores worn oval | May need line boring and bore welding, which we’ll tell you up front | Sometimes |
Is On-Site Repair Better Than Taking It to a Shop?
For most bucket damage, yes, because the machine never leaves the job. A shop repair means loading the excavator or pulling the bucket, hauling it, waiting in line, and hauling it back. On site, the repair starts when we arrive.
| Factor | On-site mobile repair | Shop repair |
|---|---|---|
| Hauling the machine or bucket | None | Load, transport and return |
| When work starts | When the welder arrives | When the shop has an opening |
| Downtime | Usually hours | Often days |
| Best for | Cracks, broken welds, adapters, wear parts | Full rebuilds, major reshaping, heavy machining |
How Much Does an Emergency Bucket Repair Cost?
It depends on the damage, so we don’t quote a number until we’ve seen photos or the bucket itself. The main factors are:
- How long and how deep the cracks are
- The type and thickness of the steel
- Whether wear parts, plate or new adapters are needed
- After-hours, weekend or holiday emergency response
- Travel distance to the machine
The cost that usually matters most is your downtime: an idle crew, a missed deadline, a rental machine. A fast, proper repair is usually the cheapest option once you count that.
When Is It Not Safe to Keep Digging?
Shut it down and call a welder if you see any of these:
- A crack you can see, especially near the hinge ears, link ears or side plate corners
- A tooth adapter that moves or rocks
- Fresh rust lines or bleeding along a weld seam, a sign of a hidden crack
- New flex, noise or play in the bucket
- Missing teeth, which let the adapters wear down fast
A bucket that fails under load can drop material, damage the machine, or hurt someone nearby. A crack is a cheap repair today and an expensive one next week.
Frequently Asked Questions
How fast can an emergency welder get to my excavator?
It depends on where the machine is and what time you call. Proud Mobile Welding offers 24/7 emergency welding, so call (512) 810-4365 and we’ll give you an honest arrival time on the phone.
How long does an excavator bucket repair take?
Most on-site repairs, like a cracked side plate, a broken weld or a new tooth adapter, take a few hours from arrival to finish. Bigger jobs, such as several cracks or full wear-plate replacement, can take longer. We’ll give you a time estimate after we inspect the damage.
Can you weld a cracked excavator bucket without removing it from the machine?
Usually, yes. We set the bucket on the ground or on blocking, shut the machine down, and weld it in place. We take it off only if the damage is in a spot we can’t reach safely.
Will a welded bucket be as strong as the original?
A correctly done repair can be as strong as the original steel, and often stronger where we add reinforcement. That depends on doing it right: removing the whole crack, preheating, and welding with low-hydrogen filler. A quick bead over a crack will fail again.
Can you replace the teeth and cutting edge too?
Yes. We cut off worn or broken tooth adapters and weld on new ones, and we replace or rebuild worn cutting edges and wear strips. Send photos so we can bring parts that fit your bucket.
Do you repair other heavy equipment besides excavators?
Yes. We repair loaders, backhoes, skid steers, dozers, crane and lift attachments, trailers, and farm equipment. If it’s steel and it’s broken, call us and describe the damage.
Are you insured?
Yes. Proud Mobile Welding, LLC is insured and bonded.
