Brazing and soldering both use filler metals to join two or more metal parts permanently. While disassembling these joints is difficult, it is not impossible. These methods fall between fusion welding and solid-state welding in the range of joining techniques.

Roll Welding is a leading technology in today’s metal fabrication, enabling you to create dependable and strong connections between different materials in industries such as aerospace, automotive or construction. Understanding the full potential of these applications is challenging without proper knowledge of roll welding. It’s like knowing the geography only makes sense when you can also read a map.

Although welding has always been essential to industry and construction, our methods and technology also change as these sectors develop. Explosive welding is one technique that is becoming increasingly popular; it’s a process that sounds as dramatic as it is useful. However, what is explosive welding exactly, and why is it regarded as the next major innovation in the joining of the materials industry? Let’s explore this in more detail in this article. So, let’s begin.

Resistance welding (RW) encompasses a range of fusion-welding techniques that achieve coalescence through a mix of heat and pressure.

Electron beam welding (EBW) is a technique that achieves coalescence using a focused stream of high-velocity electrons directed at the weld joint.

Oxyfuel Gas Welding (OFW) is a welding method that uses oxygen and a mixture of different fuels to produce a flame. The main distinction between

Arc welding is the name given to a class of welding processes that melt and fuse metal together using an electric arc as the heat source. To create a joint between the metals, this method may or may not need pressure or filler metal. 

Ultrasonic welding (USW) is a solid-state welding process where two components are joined by applying high-frequency oscillatory shear stresses while under modest clamping force. This procedure, which is frequently employed in lap welding (as shown in Fig. below), breaks off surface coatings and permits close contact between the components, forming a strong metallurgical bond.

Diffusion welding (DFW) is a solid-state welding technique that produces a strong bond by facilitating diffusion and coalescence under controlled conditions using heat and pressure. Because it may prevent common metallurgical difficulties observed in conventional welding procedures, this specialized technology is vital in the field of metallurgy.
