2008年1月15日 · Shafts are critical components of many machines, and a damaged shaft can hamper or halt production. Some failed shafts can be repaired and others can't. This article can help you determine which can be repaired and what to consider when attempting repairs.

Shaft Damage and Failure Repair welding of shafts is performed for a variety of reasons. Damage to be repaired includes, in general order of increasing relative severity: • Abrasive wear damage • Adhesive wear damage and fretting • Corrosion – uniform or pitting • Mechanical alteration (e.g., dents and gouges)

2015年3月13日 · After a second attempt with the same results, I turned another shaft. I'm using a Lincoln Weld-Pak 100 flux core welder. What I'm wondering is, is this a product of the flux core process, or my lousy technique? Will it improve if I convert my flux core to MIG? Or do I just need to practice my welding more?

2023年3月22日 · Proper welding can provide temporary, and sometimes permanent, shaft repair. Weld repair of damaged shafts can prevent catastrophic failures and minimize downtime. Repairs are typically done by in-house maintenance departments, local machine shops, and original equipment manufacturers (OEM’s).

In this video/article, we showcase masterful welding skills used to restore a damaged shaft to its original strength and functionality. Whether you’re a professional welde...more. Witness the...

How do you save an expensive Stainless steel shaft that has been bent and worn down? Overlay it using TIG welding and then machine it down. Today we are going to look at a 304 stainless steel rotor shaft that was bent, and grooved out on the seal surface in places needing to be built back up to within specifications...

2004年6月8日 · It depends on what the area on the shaft does. If it is a bearing fit, then thermal spray is the process to use. It produces a mechanical bond, with no metallurgical affect to the shaft. If it is an area that sees bending or dynamic loads, thermal spray may not be suitable. Plasma spray may work in that case.

2007年11月27日 · We have an 18" diameter shaft of 4140 that has had grooves worn into it and we plan on machining the grooves down to 0.030" below the original surface, fill the newly machined grooves up with weld material, then machine the surface back down to original dimensions. What special precautions should be taken when doing this?

To get even close to straight you will have to straighten it post weld. We used to bore things like this in a lathe and drive a small pin to line them up but without a lathe you can't do that. Alternately we sometimes cut the shaft behind the break and weld on a larger diameter piece and then machine it down to spec.

Friction welding provides a high-strength, cost-effective solution to join sections of shafts together. The result is complete metal fusion without the need for fluxes, fillers, gasses, or an external heat source. The solid-state process requires minimal joint preparation and eliminates the possibility of porosity or slag inclusion.
