Projection welding process It is a set of resistance welding processes wherein Unionization is produced by the heat received from resistance to electric current flow through the work parts held together under pressure by electrodes. The projection welding process is very similar to the spot welding process. Multiple welds are made in each operation, whether […]

Welding of Plastic    Preface                   The concept of plastic welding is nearly eight decades old when German chemists and technicians began a strict search for substitute materials in 1933 due to a shortage of non-ferrous metals. Two years later, in 1935 polyvinyl chloride became available on an […]

Seam welding is a resistance welding process wherein coalescence is produced by heating the job with an electrical resistance (obtained by an electric current (flow) through work parts) held together under pressure by circular rolling electrodes on the fraying surface. Seam welding Usually, an overlapped resistance-spot weld is produced by Resistance seam welding. In this […]

Braze welding process Braze welding process is a method of joining materials together where a non-ferrous filler metal with a melting point, below that of the base metal but above (427 0C )is used. By this process, a groove fillet plug or slot weld can be welded easily. Brazing and Braze welding process There is […]

Ultrasonic welding   The Ultrasonic welding process is a type of solid-state welding process wherein welding is done by the local application of high-frequency vibratory energy to workpieces, held together under pressure. Introduction Ultra Sonic Welding is a solid-state welding process. Its first use began around the 1960s with toy making. Ultrasonic welding is a solid-state […]

Stick welding Usually stick welding is known as SMAW welding process wherein a flux-coated stick electrode is used to fill the joint. In this process, the electrode is used as a filler metal (consumable electrode), also carries the electric current to obtain desired heat. Stick welding is used for the welding of most common metals and […]

Stainless steel is also known as corrosion-resistant steels. Due to its versatility, durability, and affordability, its use is steadily growing worldwide. Welding of Austenitic stainless steels Stainless steel welding techniques differ from carbon steel or alloy steels. Austenitic stainless steels show the following differences compared to common carbon steels: In austenitic stainless steels the electrical […]
