ERW管與（yǔ）埋弧焊管的焊（hàn）接方式有顯著的不同，采用的是無填充金屬的壓力焊（hàn）接方式， 焊縫中沒有填充其他成分，靠高頻電流的集膚效應和臨近效（xiào）應（yīng）， 使板邊瞬間加熱到焊接溫度，由擠壓輥（gǔn）擠壓形成鍛造組（zǔ）織的焊縫。 高品質的鋼管（guǎn）要求采用焊縫線上或離線熱處理，使焊區組織細（xì）化， 優質ERW焊管的焊縫可以（yǐ）達到與母材相同的韌性水準，這是埋弧焊接工藝無法達到的。
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（hàn） Electric fusion welding 的第一字母的縮寫
Abbreviation for the first letter of Electric fusion welding
埋弧焊(SAW)-電熔焊(EFW)的（de）一種，就是（shì）通（tōng）過一個或幾（jǐ）個自耗電極與工件（jiàn）之（zhī）間對金屬加熱（rè）使金屬之間結合中的一種工藝，電弧使金屬和填充材料充分融化，不（bú）需要加壓（yā），填充金屬部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（huà）氣體保護焊(GMAW)--電熔焊(EFW)的一種，這種工藝（yì）與埋弧焊類似，但它的保護是來自於惰性氣體，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（shì）埋弧焊的（de）一種，帶有一條（tiáo）螺旋焊縫（féng）。
Spiral welding - This is also a submerged arc welding with a spiral weld.
