Can anyone describe me what is âBUTTERINGâ stands for in welding joint. If it is done before depositing the weld metal on job, is it necessary to remove the same by back chipping. Mr. Das, Buttering is a technique in which weld is applied to the surface in order to acheive desired properties or required dimensions. For example in fit-up/butt joint, if distance between two butting members is excess, buttering is done on one member to reduce the gap.
TIG Welding. TIG Welding, also known as Gas Tungsten Arc Welding (GTAW), is a process that joins metals by heating them with an arc between a tungsten electrode (non-consumable) and the work piece.The process is used with a shielding gas and may also be used with or without the addition of filler metal.The primary variables in TIG Welding are arc voltage (arc length), welding current, travel speed and shielding gas composition. The amount of energy the arc produces is proportional to the current and the voltage.IG Welding. TIG Welding, also known as Gas Tungsten Arc Welding (GTAW), is a process that joins metals by heating them with an arc between a tungsten electrode (non-consumable) and the work piece.
