Welding wire and rod

Welding wire and electrode are the core filling materials in the welding process and are widely used to fill metal gaps and achieve high-quality connections. The welding materials provided by Jiangsu DZX Technology Co., Ltd. are designed with a variety of high-quality alloy formulas to ensure that the welds have excellent strength, corrosion resistance, and perfectly match the base metal in various industrial applications.

Commonly used grades (AWS standard / refer to Russian standard): ERNiCrMo-3 (corresponding to domestic: Cr20Ni65Mo9V, Russian standard: Св-ХН65МВУ), ERNiCrMo-4 (corresponding to domestic: Cr15Ni65Mo16W, Russian standard: Св-ХН65МВУ), ERNiCrFe-3 (Reference Russian standard: Св-ХН35ВТ), ERNiCrFe-7 (Reference Russian standard: Св-ХН35ВТЮ), ERCuNi (Reference Russian standard: Св-МНЖМц 28-2.5-1.5), ERNi-1 (Pure nickel welding wire, Russian standard: Св-НП-2)

Cast Iron

Cast iron welding rods and wires are specially used for the repair and welding of cast iron parts, and are widely used to repair defects in engine bodies, machine tool beds, gear boxes and various castings. The cast iron welding materials provided by Jiangsu DZX Technology Co., Ltd. have excellent crack resistance and good cutting performance, and can effectively solve the difficulties in cast iron welding.

Frequently Asked Questions (FAQ)

What are the differences between the welding cores of Z308, Z408 and Z508 cast iron electrodes?

Z308 is a pure nickel-core welding rod (ENi-CI, refer to the Russian standard Св-НП-2); Z408 is a nickel-iron core welding rod (ENiFe-CI, refer to the Russian standard Св-НЖ-13); Z508 is a nickel-copper core welding rod (ENiCu-CI, Monel type). All three are cast iron repair welding materials, and the page emphasizes their crack resistance and cutting performance.

What is the difference between Z208 and Z308? What cast iron are they used for?

What are the reference values for hardness, heat resistance and strength of cast iron welding consumables?

What workpieces can be repaired with cast iron welding consumables? Why is crack prevention important?

Used to repair defects in engine blocks, machine tool beds, gear boxes and various castings. Cast iron is sensitive to welding shrinkage and prone to cracking. The welding materials on this page are mainly composed of nickel, iron, manganese, and copper. They have excellent toughness, can effectively prevent welding cracks, and ensure that they can be machined after welding.

What are the characteristics of ERNi-CI cast iron welding wire?

ERNi-CI is a nickel-based cast iron welding wire (refer to the Russian standard Св-НП-2). The page states that it is suitable for all-position welding; the wire diameter is 0.8-3.2mm, of which the 0.2-0.8mm precision diameter is used for precision repair of small cracks. It is packaged in 5kg, 15kg/roll; the welding rod diameter is 2.0-5.0mm, and the length is 300/350/400mm.
