Not all welding processes require filler metal. Autogenous welding processes only require part of the existing base metal to be melted and this is sufficient, provided that the joint is already mechanically close-fitting before welding. Forge-or hammer welding uses hammering to close up the hot joint and also to locally increase its heat.
As with all welding processes, the proper electrode must be chosen to obtain the required mechanical properties. Operator skill is a major factor as improper electrode manipulation or machine setup can cause porosity. Flux-cored arc welding machine. Another type of FCAW uses a shielding gas that must be supplied by an external source.
SolidOx was the brand name for welding equipment produced by Cleanweld Products for do-it-yourself [1] [2] welding enthusiasts from 1965 until at least the early 1980s; the SOLIDOX name was registered as a trademark in 1968.

Spot welding can keep the battery from getting too hot, as might happen if conventional soldering were done. Good design practice must always allow for adequate accessibility. Connecting surfaces should be free of contaminants such as scale, oil, and dirt, to ensure quality welds. Metal thickness is generally not a factor in determining good welds.
Hot gas welding, also known as hot air welding, is a plastic welding technique using heat. A specially designed heat gun, called a hot air welder, produces a jet of hot air that softens both the parts to be joined and a plastic filler rod, all of which must be of the same or a very similar plastic.
