ERW管與埋弧焊管的焊接方式有顯著的不同，采用的是無填充金屬的壓力焊接方（fāng）式， 焊縫中（zhōng）沒有填充其他成分，靠高頻電流的集膚效（xiào）應和臨近效應， 使板邊瞬（shùn）間加熱到焊接溫度，由擠壓輥（gǔn）擠壓形成鍛造組（zǔ）織的焊縫。 高品質的鋼管要求采用（yòng）焊縫線上或離（lí）線熱處理，使焊區組織細（xì）化， 優質ERW焊管的焊（hàn）縫可以達到與母材相同的（de）韌性水準，這是埋弧焊（hàn）接工藝無法達到的。
ERW pipe and submerged arc welded pipe are welded in different ways. Pressure welding without filling metal is adopted. There is no filling other components in the weld. By skin effect and proximity effect of high frequency current, the edge of the plate is heated instantaneously to the welding temperature, and the forged weld is formed by extrusion roll extrusion. High quality steel pipe requires on-line or off-line heat treatment to refine the structure of weld zone. The weld of high quality ERW pipe can reach the same toughness level as the base metal, which can not be achieved by submerged arc welding technology. 電熔焊 Electric fusion welding 的第一字（zì）母（mǔ）的（de）縮寫
Abbreviation for the first letter of Electric fusion welding
埋弧焊（hàn）(SAW)-電熔焊(EFW)的一種，就是通過一個或幾個自耗電極與工件之間對金屬加熱使金屬之間結合中的一種工藝，電（diàn）弧使金屬和填充材料充分融化（huà），不需要加壓，填充金屬部（bù）分勤工全部來自於電極。
Submerged Arc Welding (SAW) - Fusion Welding (EFW) is a process that combines metal by heating one or more consumable electrodes with the workpiece. The arc melts the metal and filler material sufficiently without pressure. The filler metal part of the worker comes from the electrode.
熔化氣（qì）體保護焊(GMAW)--電熔焊(EFW)的一種，這種工藝與埋弧（hú）焊類似，但它的保護是來自於惰（duò）性氣體，效果會更好。
Melting gas shielded welding (GMAW) - a kind of electric fusion welding (EFW). This process is similar to submerged arc welding, but its protection comes from inert gas, and the effect is better.
螺旋焊---這也是埋弧（hú）焊的一種，帶有一條螺旋焊縫。
Spiral welding - This is also a submerged arc welding with a spiral weld.
