Plasma arc spraying

Plasma Arc Spraying PLASMA ARC SPRAYING is a coating process wherein a powdered metal melts by high heat obtained through plasma arc and then carried out to the workpiece surface in a molten state by the high velocity of the…

Electric Arc Spraying

Electric arc spraying system is a popular coating method as it is comparatively more efficient and cheaper than other processes. This process is accomplished by melting the filler metal at a high temperature obtained from an electric arc between two…

Metal Spraying

Metal spraying
Metal spraying is a process whereby molten metal is applied in a form of a fine spray to the surface of the base metal. The molten metal binds completely with the surface of the workpiece as a form of coating.

Stress Relief: Heat Treatment of Weldments

stress relief

INTRODUCTION The welding stresses introduced into the structures due to welding sometimes increase to higher values ​​as the yield strength of the material.. The problem of welding stress was not taken seriously until the construction of large structures by fusion…

Maintenance of welding equipment

Whether it is gas, arc or resistance welding equipment, little preventive maintenance can save us from large future expenditures. Introduction Barely any modern industrial plant is without welding equipment for both production and maintenance today. Welding has become a necessary…

Flux in welding operation

weldtech

Flux Flux is used to protect the molten metal from all types of atmospheric contamination. In Gas welding, the metal is heated in air, oxygen from the air combines with the metal to form oxides that result in poor quality,…
