Aluminum welding wire ER5356 ER4043 manufacturers offer price

Aluminum wire, aluminum content ≥99.5%, has an excellent corrosion resistance, high thermal and electrical conductivity, and excellent workability. Material anodized, the ideal color when required, is recommended for welding 1000 series aluminum alloy. Typical chemical composition: Si≤0.03, Cu≤0.002, Zn≤0.013, Fe≤0.18, Mn≤0.003, AL margin widely used in railway locomotives, power, chemical, food and other industries. Executive GB10858-89 standard aluminum and aluminum alloy wire is widely used in aluminum and aluminum welding and oxygen - acetylene gas welding as filler material. Wire selection, mainly based on the type of base material, to respect the joint crack resistance, mechanical properties and corrosion resistance and other requirements into account. Sometimes, when an item is selected as the main contradiction wire to solve this problem mainly from the start. Taking into account other aspects requirements. As in the general case, the welding of aluminum and aluminum alloy components are used with the base material of the same or similar grade wire, so you can get good corrosion resistance, but the welding heat tends to crack when a large heat strengthened aluminum, select the wire, mainly to solve the crack resistance from the start, when the wire and the base metal composition can vary widely. A typical selection of aluminum and aluminum alloy welding wire as follows. Main products: aluminum wire, aluminum welding, wear, abrasion resistant wire, aluminum welding (ER4043, ER4047, ER5356, ER1100) (Size: 1.0,1.2,1.6,2.0,2.5,3.0) SAL4047 oxygen welding, need with flux to use. 2. Prevention of repeated testing ⑴ choose the right welding specifications; ⑵ holding the gun right angle; ⑶ strengthen welder skills training; ⑷ choose the right tip diameter; ⑸ strive to make the welding arc in the groove strictly; weld carefully before ⑹ Cleanup aluminum wire, welding pieces; to ensure the protection of the purity of the gas. Copper and aluminum wires for between copper and aluminum brazing flame or high frequency brazing, welding can achieve a firm brass and aluminum, copper and aluminum or copper and aluminum between. Under certain circumstances also be applied to the welding between aluminum and aluminum. In the copper and aluminum wire with flux, non-corrosive, easy to operate, can achieve online production. Operating temperature range is about 410-430 ℃. Wire Size (mm): 0.1 --- 5.0 (mm) packed in 1 kg / roll, 2 kg / roll, 3 kg / roll, 5 kg / roll, 10 kg / roll, 15 kg / roll, 20 kg / Volume chemical composition of the implementation of standards:. GB / T3190-1998 wire standard: GB10858-2008 equivalent to ANSI / AWS A5.10-92 The company has passed ISO9001: 2008 quality management system certification, product packaging: shrink film sealing + carton + Strapping delivery: straight (long 1m, 10 kg / box) and disk loading (7 kg / plate) manufactured products have certification, provide material book Mimoro brand aluminum and aluminum wire products AC welding applications, not need flux, it is not recommended to weld two welding machine. First, poor weld weld seam ripples difference mainly in the pretty, not bright; weld bent not straight, varies in width, the joint too much; weld central projection, both sides of the flat or depressed; weld Man overflow and so on. 1. Causes ⑴ welding specification poor choice; ⑵ torch angle is incorrect; ⑶ unskilled welder; ⑷ tip aperture too; ⑸ welding arc is not strictly aligned with the groove center ⑹ aluminum wire, weldment and protective gas contains water; Second, aluminum and aluminum alloy weld crack crack is generated in the weld metal crystallization process called thermal cracking, also known as crystal crack. In the form of longitudinal cracks, transverse cracks (often extended to the base metal), as well as the roots of the crack, crater cracks and so on. Cracks will reduce structural strength, or even cause a sudden destruction of the whole structure, and therefore is totally not allowed. 1. Causes ⑴ welding gap aspect ratio is too large; ⑵ cooling weld crater end of the fast; ⑶ aluminum wire does not match the component and the base material; ⑷ technique is incorrect. 2. appropriate measures to prevent ⑴ increase or decrease arc voltage welding current is reduced to widen the weld penetration ⑵ appropriate to fill the crater and attenuating measures to reduce the cooling rate; ⑶ ensure a reasonable match of aluminum wire and the base material ; ⑷ select the appropriate welding parameters, welding sequence, an appropriate increase in welding speed, you need to warm-up measures to be taken preheat Features: aluminum wire, aluminum content ≥99.7%, has excellent corrosion resistance, high thermal and conductive properties, as well as excellent workability, anodized after having a good color match ratio.
