Laser welding machine store UK 2024: The use of lasers for welding has some distinct advantages over other welding techniques. Many of these advantages are related to the fact that with laser welding a ‘keyhole’ can be created. This keyhole allows heat input not just at the top surface, but through the thickness of the material(s). The main advantages of this are detailed below: Speed and flexibility Laser welding is a very fast technique. Depending on the type and power of laser used, thin section materials can be welded at speeds of many metres a minute. Lasers are, therefore, extremely suited to working in high productivity automated environments. For thicker sections, productivity gains can also be made as the laser keyhole welding process can complete a joint in a single pass which would otherwise require multiple passes with other techniques. Laser welding is nearly always carried out as an automated process, with the optical fibre delivered beams from Nd:YAG, diode, fibre and disk lasers in particular being easily remotely manipulated using multi-axis robotic delivery systems, resulting in a geometrically flexible manufacturing process.

Laser beam welding can achieve good penetration, typically up to about 0.040 in. deep in steel for a 350-watt laser. Laser welding can usually join crack-prone materials, such as certain types of steel and aluminum, and, much like EB welding, lasers can join dissimilar materials. The alternative to pulsing is continuous wave (CW). As the name implies, CW lasers utilize a laser beam that is on continuously – from the start to the end of the weld cycle. CW lasers are useful for cutting applications or when weld speed is important. For example, an automated GTAW machine might have a welding speed of 10 inches per minute (IPM), while a CW laser could easily run at 100 IPM.
Resistance or pressure welding uses the application of pressure and current between two metal surfaces to create fusion. Workpieces are placed in contact together at high pressure with a current passing through the contact point. The resistance in the metals generates heat which fuses together the metal surfaces of the workpiece. Resistance spot welding (RSW) uses two electrodes to press together overlapping metals while a welding current is applied through the resistive metals. Heat is generated and the metal surfaces fuse together to create a weld joint in the shape of a button or nugget. Metals are fused using large amounts of energy in a short time span (approx. 10-100 milliseconds) joining the workpieces almost instantaneously. The area around the weld nugget stays unharmed by the excessive heat, thus the heat-affected zone is minimal with spot welding. Discover additional details at here.

We hope this buying guide will help you in choosing the welder that most suits your needs. After further explanations of the welding process and what to look for when buying, there will be a list of ten well-known metal inert gas welders that will each be reviewed briefly.
PACE Fume Extraction Systems provide effective odor reduction from the limited use of adhesives, solvents, and other compounds during handheld drilling, milling, or grinding operations. The filter cartridges are disposable, which makes them easier to use for fume extraction. Sturdy Steel Case and Lightweight Build Quality The Arm-Evac 150 comes with a steel case, which I found to be quite sturdy. It also has a dependable brushless motor that doesn’t need expensive routine maintenance. The overall unit is built with 20-gauge steel, which is ESD-safe. This tiny, low-profile machine will fit anywhere you need, and it comes with lockable casters for convenient mobility and transportation. The compact unit weighs only 20 pounds which makes it extremely lightweight.
