For any of these processes, joint surfaces and any filler metal must be clean.

      Thus, if a welder’s duty hours can be expressed in terms of duty cycle defined as actual welding time as a percentage of total duty time, it may be easier to select a process for a given job. Higher duty cycles can be achieved on welding long fillet joints compared with short run welds on a workpiece of complicated :// These are SMAW (shielded metal arc welding), GMAW (gas metal arc welding), and TIG (tungsten inert gas) welding. There are important differences in the process and capabilities of each, so it is important to understand their unique characteristics. SMAW. SMAW stands for shielded metal arc welding. This is also commonly called ‘stick’ ://

Dear Colleagues, Welding is one of the technological fields with the greatest impact in many industries, such as automotive, aerospace, energy production, electronics, the health sector, etc. Welding technologies are currently used to join the most diverse materials, from metallic alloys to polymers, composites, or even biological Welding of metals is applied on a very wide scale, especially for building up structures by welding of steel plates and girders of different cross sections (I-beams, U-beams, angle beams).

Welding provides many structural design options which cannot be simply realized with other production ://   Friction stir welding (FSW) is recent technique in welding that utilizes a rotating welding tool to generate frictional heat and plastic deformation at the welding place, resulting in the creation of the joint while the material is in the solid state.

Friction welding is a type of forge welding, i.e. welding is done by the application of   With friction welding usually rotational symmetrical parts are rotated while being pressed together, thereby generating heat of friction which causes the parts to weld.

This process also enables to weld aluminium to steel. A more recently developed process is friction stir welding (FSW). In fig. 4 the principle of friction stir welding is.
