There are many welding techniques, including TIG and MIG welding. So what are they and\u00a0 what are the applications to stainless steel welding? Let’s find out now with DAI DUONG<\/span><\/p>\n N\u1ed9i dung chính<\/p> Firstly, let’s learn the concepts of TIG welding and MIG welding to get an overview and the most basic of these two common welding methods.<\/span><\/p>\n TIG (Tungsten Inert Gas) welding is an arc welding with a non-melting electrode in a protective gas environment. These protective gases are helium or argon, argon combined with helium, argon combined with hydrogen or oxygen.<\/span><\/p>\n TIG welding is done by bringing one end of the tungsten electrode close to the other electrode end attached to the material welded. The process of producing arcs and melting welding rods helps to cement the welds. This weld is protected by inert gas, which is the gas mentioned above.<\/span><\/p>\n MIG (Metal Inert Gas) welding is a fusion arc welding in a protective gas environment. The protective gases are Argon, Helium or Argon combined with Helium, CO2; CO2 + 02; C02 + Argon … helps pushing air out of the welded area. MIG welding is done by supplying molten electrode, arc and molten metal protected by inert gases.<\/span><\/p>\n \u00a0TIG welding and MIG welding have different characteristics, advantages and disadvantages as well as applications.<\/span><\/p>\n – Do not use soldering or additives\u00a0 not being able to create slag.<\/span><\/p>\n – Easy to observe and check the arc.<\/span><\/p>\n – High temperature<\/span><\/td>\n – Electric current and arc are maintained automatically by the machine, welding speed, electrode angle are maintained by the mechanic.<\/span><\/td>\n<\/tr>\n – Welding both thin and thick metal, adjustable welding parameters from several amps to several hundred amps.<\/span>– Welding many metals and alloys.<\/span><\/p>\n –\u00a0 beautiful\u00a0 quality of clean welds, no dullness, no sediment and\u00a0 controlling the shape of welds as you like<\/span><\/p>\n<\/td>\n – High productivity, 2.5 times higher than manual arc method.<\/span>– Welding with metals such as steel, aluminum, stainless steel …<\/span><\/p>\n – Not generating toxic during arc process.<\/span><\/p>\n – Temperature focuses on a certain area.<\/span><\/p>\n – good quality of welding, less bent, warping.<\/span><\/p>\n – Save energy, labor time<\/span><\/p>\n – Welder does not need high skills.<\/span><\/td>\n<\/tr>\n – Requirements on skill, experience and skill of the welder<\/span><\/p>\n – Because the materials, equipment or devices for TIG welding are expensive -> TIG welding products are often expensive, large quantities are not competitive compared to other welding methods.<\/span><\/p>\n<\/td>\n – Productivity is not high<\/span>– Requirements on skill, experience and skill of the welder<\/span><\/p>\n – Because the materials, equipment or devices for TIG welding are expensive -> TIG welding products are often expensive, large quantities are not competitive compared to other welding methods.<\/span><\/p>\n<\/td>\n<\/tr>\n – Steel alloys such as stainless steel, carbon steel, black steel.<\/span><\/p>\n – Other alloys such as copper, aluminum, magnesium, nickel, cast iron …<\/span><\/p>\n – Welding needles: Based on welding materials to select the appropriate welding needle.

However, because of the characteristics of stainless steel, the choice of TIG welding is considered optimal to ensure the best welding quality, without warping or dulling.<\/span><\/p>\n Step 1:<\/i><\/b> Prepare stainless steel materials before welding<\/span><\/span><\/p>\n Clean all stainless steel materials before welding. If the impurities remain on the surface, when welding, it is easy to leave pitting or crack welds. Remove dirt, impurities on the surface of stainless steel with a wire brush, wipe oil with specialized solvent to ensure the cleanest surface.<\/span><\/p>\n Step 2:<\/i><\/b> Select the appropriate protective gas<\/span><\/span><\/p>\n The most suitable protective gas when welding TIG with stainless steel materials is usually Argon or has a high proportion of argon (Argon 75% + CO2 25%).<\/span><\/p>\n As for 316 stainless steel, it is advisable to choose a protective gas mixture with a proportion of 90% Helium + 8% Argon + 2% CO2.<\/span><\/p>\n Step 3:<\/i><\/b> Apply TIG welding technique on each specific type of stainless steel product<\/span><\/span><\/p>\n With 2 straight pipes in succession:<\/span><\/p>\n With 2 304 stainless steel tubes forming a certain angle:<\/span><\/p>\n It should be noted that because the material is tubular, it is easy to leak when welding or to leak arc into the inside of the pipe wall.<\/span><\/p>\n Inox welding requires not only good technique and workmanship, but also TIG welding machines that are suitable for maximum weld quality, optimal performance and performance.
