Cold welding or contact welding helps do away with this challenge because they work on the principle of physics and material science. Cold welding is an interesting process that allows the joining of metals without any heating requirements.

Arc welding techniques are as diverse as the finished products they produce, making it imperative that you select the method that best suits your project requirements. Even while both MIG and TIG welding uses an electric arc to make the weld, the two processes are very distinct, and utilizing the wrong one can cause various problems.
