Скачать или смотреть MIG welding (CO2) GMAW process advance welding

MIG welding, yaani Metal Inert Gas welding, ko Gas Metal Arc Welding (GMAW) bhi kaha jata hai. Is process mein, ek continuous wire electrode use hoti hai jo welding gun ke zariye molten pool mein feed hoti hai.

Key Points:

Shielding Gas: Is process mein CO2 (carbon dioxide) ya mixed gases (jaise argon aur CO2 ka combination) ko shielding gas ke roop mein istemal kiya jata hai. Ye gas welding arc ko protect karti hai aur molten metal ko oxidation se bachati hai.

Welding Equipment: MIG welding ke liye welding machine, welding gun, wire feed mechanism aur shielding gas cylinder ki zaroorat hoti hai.

Process: Jab welding gun se electrode feed hota hai, to electrical arc generate hota hai jo wire aur workpiece ke beech mein heat produce karta hai. Ye heat metal ko melt karke ek molten pool banata hai, jo jab thanda hota hai, to weld joint bana leta hai.

Applications: MIG welding ko various industries mein istemal kiya jata hai, jaise automobile manufacturing, construction aur general fabrication, kyunki ye process fast, efficient aur versatile hai.

Advantages: Iski advantages mein high welding speed, less spatter, aur better control shamil hain. Ye process beginner-friendly bhi hota hai, kyunki ismein technique seekhna aasaan hota hai.

Disadvantages: CO2 gas ki use ke wajah se thoda zyada spatter ho sakta hai, aur weather conditions (jaise wind) is process ko affect kar sakte hain.

Yeh process modern welding applications mein kaafi popular hai, kyunki yeh high-quality welds produce karta hai.
