Process

Powerful Multi-process Welding Platform,Offer You Perfect Welding Experiences

Ferrous metal is the most-used and most-welded metal in all metals. In recent years, with the popularity of high-strength steel and ultra-high-strength steel, the industry has higher requirements for welding equipment. Therefore, we rolled out the multi-process welding platform targeting at the welding of ferrous metal.

1) Cold-arc welding: low heat input, suitable for lap welding, thin-plate welding and solid wire surfacing

Technical features:

A.Low heat input, seam beautiful

B. Arc burns stale, few spatter

C.Arc soft, molten pool calm

D.Cold-arc welding is DC welding, both 80%Ar+20%CO2 and 100%CO2 can be used

Cold-arc vertical downward welding

2) Root welding: suitable for all-position bottom welding, especially the welding of pipes in petrol and chemical industry, and so on

Technical parameters:

A.Can take the place of TIG welding to do backing welding, and its speed is 3-4 times of TIG welding

B.Heat input can be accurately control, similar to TIG welding

C.Few spatter, seam beautiful

D.In root welding, the welding meat is smooth, and backside of welding seam will not be sunken, but bulged

E. Suitable for metal-cored wire and sold wire

Front side of root welding

Back side of root welding

3) Vertical up welding: suitable for all kinds of vertical up fillet welding or cover weld

Technical features

A. Heat input can be accurately controlled

B.Few spatters, clear ripples can form automatically

C.DC cold arc and hi-speed pulse arc work alternatively, work frequency and duty cycle can be set independently

D.While the work frequency of DC cold arc and hi-speed pulse arc is 100Hz, you can get a brand-new welding--composite arc welding

E. Suitable for welding of medium/thick plate, especially the welding of high-strength steel, ultra-high strength steel

F.High speed, beautiful seam, greatly decrease the welder’s labor intensity and decrease the technical requirements

Base welding of double-pulse vertical up welding

Cover welding of double-pulse vertical up welding

4)Hi-speed pulse: suitable for all kinds of weld

A.Suitable for 0.8, 1.0, 1.2, 1.6mm sold/flux-cored wire

B.Arc burns stable in small current, stable welding can be realized with 1.2mm wire and 50A current

C.Deep penetration, few spatter

D. High speed, no undercut

E.Can realize surfacing of nickel-based, cobalt-based, iron-based solid/flux cored wire

F. With all functions of DSP (TG3)

Single-pulse horizontal fillet welding to carbon steel

5)Hi-speed pulse welding: suitable for all kinds of flat weld, fillet weld, transverse weld

Technical parameter

A. Few spatter, ripple beautiful and clear

B.Strong and weak pulse convert quickly, arc sounds clearly

C. High speed, no undercut, low heat input

D.Suitable for perfect welding of medium and thick plat

Double-pulse horizontal fillet welding to carbon steel

Double-pulse horizontal fillet welding to stainless steel
