LT·J422

Conform to Standard GB/T 5117 E4303

ISO 2560-B-E 43 03 A

Specification:Welding electrode E4303 (J422) is calcium-titanium coated carbon steel electrode. It has very good welding uasability that enables it to operate on AC/DC, performs all-position welding,has stable arc,removal of slag is easy and has good bead appearance. Its good mechanical propertities give it very good low temperature toughness.During the application,its characteristic of easy maneuverabilities offers easy striking,easy re-striking and good control of welding speed,which enables the welders to have desired weld path and penetration of the arc.

Purpose:It is used for welding of low carbon ssteel structure and low strength grade of low alloy steel structure.Such as Q235,09Mnv,09Mn2 etc.

As part of our development strategy, we have always been focused on the complete production process model. We believe this will bring us synergy effects. Therefore, recently, a new product, namely welding consumables, has been added to our catalogue. It will cover all series such as gas shielded solid welding wires, flux-cored welding wires, submerged arc wires, argon arc wires, etc., as well as medium and heavy plate series (thickness 6-800mm). Width: 1500mm-3650mm, maximum single weight: 60t

Our LT welding wire has two main advantages:
A fully integrated production process, that is, supported by the world-class upstream steel manufacturing facilities of the same group company.
The newly developed production process, which adopts the latest technologies and know-how, namely fully automatic production, will ensure quality control.
Our advantages of medium and heavy plates:
Complete electric furnaces and off-furnace refining equipment
The rated capacity of the ultra-high power electric furnace is 115 tons, and the maximum steel output per furnace is 130 tons
It has two 115-ton LF refining furnaces and one double-station VD furnace
The largest-sized steel ingots and continuous casting billets
The largest flat steel ingot is 60 tons, and the largest plum blossom steel ingot is 270 tons
The maximum single weight of the ingot steel plate: 60 tons (forged and rolled combined process)
Continuous casting adopts the techniques of dynamic light pressing, dynamic secondary cooling and heavy pressing
The maximum cross-sectional specification of the continuous casting billet is 460*2600*3600mm
Complete rolling line equipment
Advanced split vertical rolling mill
