Best laser safety glass online shop UK: For precision welding requirements, the choice is usually between electron beam welding and laser beam welding. Sometimes other types of fusion welding, such as GMAW or GTAW, might be an option, but arc welding processes don’t have the penetration, small heat-affected area, pinpoint precision, and weld purity of EB and laser welding. Electron beams and lasers can be focused and aimed with the exceptional accuracy required to weld the smallest of implantable medical devices, and yet also deliver the tremendous amounts of power required to weld large spacecraft parts. Electron beam and laser welding are versatile, powerful, automatable processes. Both can create beautiful welds from a metallurgic and an aesthetic perspective. Both can be cost-effective.

No Electrode Required – In arc welding, electrodes are an essential part of the welding system. Welding electrodes are long wires connected to your welding machine. These wires/electrodes create an electric arc. The electrodes meltdown by heat and fuse the metals. However, you do not need to use electrodes in the case of laser welding. The laser welding systems use intense heat to join the parent metals together without the help of an electrode. The weld doesn’t contain traces of melted electrodes, giving a superior finish to the final product. Fusion of Metals with Dissimilar Physical Properties – The laser welding system is aligned and guided by optical instruments for accurate results. The laser beam can be set at the desired focal length for the product you’re working on. The focal length of the laser beam is adjustable to use different laser welding modes. While using arc welding systems, customization is impossible due to a lack of versatility and low-speed processing.

Compared to the Hobart 500559 Handler 140amp MIG welder above, the MVP is a more powerful, dual voltage MIG welder for beginners. Its heavier and about $300 more to buy, but the thicknesses it can weld are greatly increased. It has several power outputs to choose from. The bottom line is that the MVP is worth buying if you need more power than the Handler 140 can offer. For beginners and pros alike, the MVP lives up to its name. This is a dual voltage machine that can weld from 24 gauge to 3/8 inches of steel. Among the metals, it can weld are steel, stainless steel, and aluminum. The MVP has 7 power settings to choose from. The spool hub can handle both 4 inch and 8 inch reels.

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. See more details at https://www.weldingsuppliesdirect.co.uk/.

The Lincoln X-Tractor Mini weld fume extractor has a 99.7% efficiency in removing welding fumes. It’s adequate for keeping your house or store fresh. 80 dBA sounds that it generates are close to nothing comparing with other fume extractors. Despite being a mini portable fume extractor, the X-Tractor Mini has versatile usability. It can be used for flux-cored welding, MIG and TIG welding, and stick welding. This portable weld fume extractor from PACE is ideal for benchtop soldering and electronic rework. The low-cost Arm-Evac 150 System includes everything you’d find in the best portable welding fume extractor. 3-stage filtration system adds immense value to its overall efficiency.
