焊接工艺是一种通过加热或加压，或两者并用，并且使用（或不使用）填充材料，使两个或多个分离的物体达到原子间结合的技术。
它广泛应用于制造业、建筑业和修理行业中，是现代工业不可或缺的一部分。
焊接方法多种多样，包括电弧焊、气体保护焊、电阻焊、激光焊等，每种方法都有其特点和适用范围。
Welding technology is a technique that achieves atomic-level bonding of two or more separate objects through the application of heat or pressure, or both,
and by using (or not using) filler material. It is widely employed in manufacturing, construction, and repair industries, serving as an indispensable part of modern industry.
Welding methods are diverse, including arc welding, gas shielded welding, resistance welding, laser welding, and more, each with its own characteristics and areas of application.
