CNC Automated Hardfacing Welding Machine

I.Description

A cladding welding machine is an automated welding device designed for specific workpieces or process requirements. It is usually composed of a mechanical system, welding power source, wire feed mechanism, control system, and necessary auxiliary devices. Its core purpose is to automatically clad a layer of alloy with special properties (such as wear resistance, corrosion resistance, and high temperature resistance) on the surface of the part to repair worn parts or enhance the surface properties of new parts.

II.Machine Feature

• Welding torch is fixed while workpiece is rotating, welding position is horizontal.
• Workpiece is clamped and rotary by fixture and supported by universal ball bracket.
• The machine has high voltage and slow wire feeding performance, which guarantees reliable arc igniting. Machine also has low welding voltage and low current for filling crater.
• It adopts push-type wire feeding mode, to guarantee feeding stability.

1.Welding torch can be adjusted up and down (pneumatic cylinder),the welding wire is fed continuously and steadily while shielding gas is ejected, and the arc is ignited the moment it contacts the workpiece base material. The concentrated high heat energy generated by the arc rapidly melts the welding wire and the base material surface, forming a molten pool, which moves at a constant speed along the path preset by the dedicated machine, and eventually the molten welding wire metal is stacked layer by layer and clad on the workpiece surface.

2.Pipe is fixed by the rotary chuck, and supported by bracket of rolling wheels. Universal ball ensures that it is flexible and convenient to rotate. Distance between supports can be adjusted according to pipe length.

3.Oscillating mechanism is composed of stepper motor, ball screw and linear rail, etc. It adopts closed type structure, shielding the process from dust and spatters. Torch oscillating frequency, oscillating scope, oscillating time, lifting distance, lifting numbers can be controlled by CNC system.
