Laser welding is a high concentration of light and heat in a small (0.2mm ~ 2.0mm) inside the spot, in an instant (0.5ms ~ 20ms) of the molten base metal wire and die. After cooling the melt, if the welding part of the base metal microstructure with the same mold, you can ensure the Welding Electrode quality; and if not, it may appear trachoma, cracks, or bonding is not strong and fall off and so on.

Choose affect the welding quality welding consumables:

1. If you choose to die with the same base metal wire with metal of the laser, the metal will melt after the microstructure is inconsistent with the mold base material, from the impact of welding quality.

2. If you choose stainless steel wire, or close to the laser welding of stainless steel materials with the same problem could occur, does not guarantee the hardness after welding. Because less carbon stainless steel, low hardness, welding after the welding bit easier to wear.

3 wire imported from Germany for different mold materials, there are different models. However, unlike welding laser welding, laser welding is a high concentration of light and heat welding, welding wire model for the choice of not very strict, as long as the base material followed by melting solder connection is good and consistent hardness can achieve a good weld quality.

The preservation of wire:

As the laser wire is alloy, not stainless steel wire, there may well save the rust. Some laser welding on the surface coated with a thin layer of rust-proof material, but not too thick coating of rust layer, or will affect the welding quality, rust-proof layer which is equivalent to impurities in the welding process. Especially welding wire mold mirror, even if it is plated rust layer.

Use wire sealed bag, put inside the moisture beads, stored in a dry environment. If on long-term air-conditioned environment, save the six months to a year will not rust.

If the wire for rust, surface rust with sandpaper to fight to the light, you can use without affecting the Aluminium Welding Electrode.

Wire model is commonly used in Germany MOLD10, MOLD50, MOLD55 and MOLD90. One diameter of 0.3mm, 0.4mm and 0.5mm wire commonly used in the domestic inventory in stock. If you want to order special wire, then from the German order, depending on order quantity may be, delivery time between one week to three weeks.

Wire models of choice, mainly based on the use of molds and hardness may be. However, the use of laser welding parameters for each different, so the choice of wire type, to the wire instructions as a reference, the laser welding parameters and operating habits.
