主要包括以下幾種:
1.手工電弧焊焊接工藝。這是最常用的焊接工藝之一,利用電弧產(chǎn)生的熱量來熔化焊條和母材,從而實現(xiàn)焊接。這種工藝操作簡便,適用于各種金屬材料。
2.埋弧焊焊接工藝。這是一種自動化焊接工藝,主要用于焊接長焊縫。在焊接過程中,電弧被埋在焊劑和母材之間,可以有效地控制焊接質(zhì)量和焊接速度。
3.氣體保護焊焊接工藝。這種工藝使用氣體來保護電弧和熔池,防止空氣對焊接區(qū)域的影響。氣體保護焊適用于各種金屬材料,焊接質(zhì)量穩(wěn)定。
4.等離子弧焊接工藝。等離子弧焊接是一種高精度的焊接工藝,適用于薄壁材料和精細零件的焊接。它利用高溫的等離子電弧來熔化母材,實現(xiàn)高質(zhì)量的焊接。
5.電渣焊焊接工藝。電渣焊是一種高效的焊接工藝,適用于厚壁大件的焊接。在焊接過程中,電流通過熔渣產(chǎn)生熱量,使焊條和母材熔化,實現(xiàn)焊接。
Common Welding Process Classifications
?
1. Manual Arc Welding?
Definition?: A widely used process where an electric arc generates heat to melt the electrode and base metal, forming a weld.
Features?:
Simple operation, adaptable to various metals (steel, aluminum, etc.).
Requires skilled workers to control arc stability and weld quality.
?2. Submerged Arc Welding (SAW)?
Definition?: An automated process ideal for long, continuous seams. The arc is buried under a layer of flux, shielding the weld from air.
Features?:
High efficiency and consistent weld quality.
Commonly used in shipbuilding, pipelines, and structural steel.
?3. Gas Shielded Welding?
Definition?: Uses inert or active gas (e.g., argon, CO?) to protect the arc and molten pool from atmospheric contamination.
Types?:
?MIG/MAG Welding?: Metal Inert Gas (MIG) or Metal Active Gas (MAG) for versatile metal joining.
?TIG Welding?: Tungsten Inert Gas (TIG) for high-precision welds (e.g., stainless steel).
?Features?:
Stable quality, minimal spatter, and clean results.
?4. Plasma Arc Welding (PAW)?
Definition?: A high-precision process using a concentrated plasma arc (up to 30.000°C) for thin materials or intricate parts.
? Applications?:
Aerospace components, medical devices, and electronics.
?Features?:
Minimal distortion and deep penetration with narrow welds.
?5. Electroslag Welding (ESW)?
? Definition?: A high-efficiency method for thick materials (e.g., heavy machinery). Current passes through molten slag, generating heat to melt the electrode and base metal.
? Features?:
Single-pass welding for thick sections (up to 300mm).
Used in pressure vessels and large structural fabrication.
