While weldability can be generally defined for various materials, some welding processes work better for a given material than others. Even within a certain process the quality of the weld may vary greatly depending on parameters, such as the electrode material, shielding gases, welding speed, and cooling rate. [1]
Processes that employ inert gases to protect the weld cannot be readily used in such situations, because unpredictable atmospheric movements can result in a faulty weld. Shielded metal arc welding is also often used in underwater welding in the construction and repair of ships, offshore platforms, and pipelines, but others, such as flux cored ...
The Canadian Welding Bureau, through CSA Standards W47.1, [3] W47.2 [4] and W186, [5] specifies both a WPS and a Welding Procedure Data Sheet (WPDS) to provide direction to the welding supervisor, welders and welding operators. The WPS provides general information on the welding process and material grouping being welded, while the WPDS ...

A welder is a person or equipment that fuses materials together.The term welder refers to the operator, the machine is referred to as the welding power supply.The materials to be joined can be metals (such as steel, aluminum, brass, stainless steel etc.) or varieties of plastic or polymer.
Gen Z has a bad reputation for being work-shy.But new research shows that couldn’t be further from the truth—the youth of today just don’t want a desk job.
Welding imperfections such as weld discontinuities. - Risk of welding in very short time. [67] Moreover research articles do not always describe the risks. Corner problem in friction welding with specific parameters time below 100 ms and conical contact surface. [67] There is a complete weld inside but corner is not welded.
