Welding and blacksmithing of trailers

Welding is a manufacturing process in which two materials, usually metals or thermoplastics, are joined by using heat to fuse the edges of the two materials together, sometimes accompanied by external pressure, and then allowed to cool, which gives them permanent hardness.[1][2][3] The welding process differs from other materials joining processes that take place at temperatures such as mixing welding and tin soldering, which are not accompanied by melting of the materials to be joined.@TravelerF150
