There are a lot of reasons why cold stitching (also known as stitch welding or metal locking) can be used to great effect when metalwork needs repaired. The technique has been around for at least 100 years when it comes to repairing machinery made of a variety of different metals though the most common is probably cast iron.
Repair services drill holes in the cast iron (or other metal) at a right angle to any crack. Those are widened into a slot and then locks are put in the slot to connect them together. Then holes are created in order to put screws that make sure the repair is watertight. In fact, the repair is often stronger when practitioners use this technique because the original metal is stitched together on the very surface of the item being repaired.
Although individual repairs will have their own particular requirements, the process of cold stitching is pretty much the same. Anything from kilns to compressors or dryers can be repaired with cold stitching. Advantages to having a technician use cold stitching to repair equipment include:
- Fixes cracks and ends up making the item stronger. It looks like the stitches people receive and acts in a similar manner.
- Repairs can be done onsite to save on downtime. Companies like Onsite Metal Stitching can respond and evaluate any problem.
- Spreads tension away from the compromised point, which places less stress on cracks that would otherwise expand.
- It doesn’t heat the metal and cause brittle problems with the metal parts later on like heating the metal would cause.
Cold stitching can also be done onsite by services such as Onsite Metal Stitching rather than bringing the broken piece of equipment into a workshop. The convenience alone makes it worth it. The end result will often be a stronger and more durable piece of equipment or machinery. The key is to make sure a reliable professional can assess the problem with whatever metal item is cracked or broken.
