The properties of welded joints mainly depend on properties of an alloy formed from the filler metal and base metal. Strength, ductility, resistance to weld cracking, gas porosity, corrosion resistance, heat treatability and other properties may be largely influenced by the degree of dilution of the filler metal.
The extent of the fusion of the base metal and dilution with the filler metal depends upon joint design, welding process used, and welding procedure. Weld cracking tendencies are generally reduced by keeping bare alloy dilution to a minimum.
The proper choice of a filler metal in welding is an extremely important factor, and in combination with the welding technique, it may play a crucial role in achieving the desired results.
This catalog is designed to introduce selectively and very generally the correlation and proper usage between base alloys and the suggested filler metal Lancaster Alloys Company has to offer. Though the welding industry is tremendously complicated and widely varied in it's nature, we hope that you will find the information we have put together here as helpful and beneficial as possible. Understanding our customer's needs and supplying them with the best weld wire possible is our most important goal.
