Currently on the market a lot of welding process, although both customers and manufacturers to meet the requirements of welding, but in this competitive market if you do not have a good equipment to increase production with the quality of the product, then it you will always be in your industry eliminated, I tell you about the current welding process are more familiar with the difference between right one, SMAW (MMA):. SMAW is a very popular, easy to use method of welding arc length is adjusted by human hands It depends on the size of the gap between the welding electrode and the workpiece. In addition, when used as an arc carrier, also welding the weld filler material. This welding method is very simple, can be used to weld almost all materials. For outdoor use, it have a good adaptability, even underwater use, no problem can most welding TIG welding electrodes welding, arc length is determined by the human hand: 2. welding technology is the principle in general arc welding based on the use of argon for metal welding consumables, through the high current causes the welding material melts into a liquid base material to be welded is formed molten pool, so that the welded metal and the welding consumables to achieve a metallurgical bond, since the In the high-temperature molten solder constantly send argon welding consumables can not make contact with oxygen in the air, thus preventing the oxidation of welding consumables, it can be welded stainless steel, ferrous metal hardware. Welding because of the large heat affected zone, the workpiece after repair often cause deformation, the hardness decreased, trachoma, partial annealing, cracking, pinholes, wear, scratches, undercut, or a combination of force is not enough internal stress injury and disadvantages . Especially in precision casting process repair small defects in the surface of the projection. Repair defects in the field of precision castings can be used to replace TIG welder cold, put a little heat due to cold welding, TIG better to overcome the shortcomings, make up the precision castings repair problems. TIG and SMAW compared to the extent of damage to the human body to be higher, high welding current density, more intense light emitted ultraviolet radiation generated by its arc, about ordinary SMAW 5 ~ 30 times, the infrared SMAW about 1 to 1.5 times, higher ozone levels generated during welding, thus, try to choose a better place Construction air circulation, or the body has great harm. For ease of evaporation of low-melting metals (such as lead, tin and zinc), more difficult to weld. 3. SAW (submerged arc welding and electroslag welding including, etc.) is an arc welding under flux layer method of burning. Stabilize its inherent quality of welding, welding production rate, no arc and smoke less, etc., making it the pressure vessels, pipe manufacturing, steel box beams and other important production of major welding methods. In recent years, although has appeared in many kinds of efficient, high quality new welding method, but still were not submerged arc welding applications in any way. Deposited metal weight from a variety of welding methods share perspective, submerged about 10%, and for years has been little change 4. Laser welding is the use of high-energy laser pulses of material to make minor localized heating within the region, the energy of the laser radiation guided through the heat transfer material interdiffusion, the material forming a particular bath melted. It is a new type of welding, the main material for the thin-walled welded precision parts, enabling spot welding, butt welding, stitch welding, seal welding, etc., aspect ratio, weld width is small, small heat-affected zone, small deformation, welding speed, weld smooth, beautiful, without treatment, or simply after welding, high weld quality, nonporous, can be precisely controlled, focused small spot, high precision, easy to automate. For now the welding process, the welding is the best laser welding, a speed, depth, small deformation. 2, the welding can be performed at room temperature or special conditions, simple welding equipment installation. For example, the laser through the electromagnetic field, the beam does not shift; laser in vacuum, air and a gas welding environment can, and through glass or transparent material beam welding. 3, can be welded refractory materials such as titanium, quartz, and is able to heterosexual welding material, to good effect. 4, after the laser focus, high power density, high power devices in welding, aspect ratios up to 5: 1 up to 10: 1. 5, can be micro-welding. After the laser beam is focused by a small spot available, and can pinpoint, can be applied to high-volume automated production of micro, small parts in welding. 6, can be welded inaccessible site, the implementation of a non-contact remote welding, with great flexibility. Especially in recent years, the YAG laser processing technology used in the fiber-optic transmission technology, laser welding technology to obtain a wider range of promotion and application. 7, the laser beam is easy to achieve a beam splitter by time and space, capable of multi-beam processing and multi-station machining, welding for more sophisticated technology to provide the conditions are primary productive forces, as long as the pace with the times, in order to create more for business good value. Select the laser welding of stainless steel, is currently a lot of people an essential condition of success. If you are willing to try, willing to change, you can always contact us!
