ERW管與埋弧焊管的焊接方式有顯著的不同，采用的是無填（tián）充金屬的壓力焊接方式（shì）， 焊縫（féng）中沒有填充其他成分，靠高頻電（diàn）流的集膚效應和臨近效應， 使板邊瞬間加熱到（dào）焊接溫度，由擠壓輥擠壓形成鍛造組織的焊縫。 高（gāo）品質的鋼管（guǎn）要求（qiú）采（cǎi）用焊縫（féng）線上或離（lí）線熱處理，使焊區組織（zhī）細化， 優質ERW焊管的（de）焊縫（féng）可以達到與母材相同的韌性水準，這是埋（mái）弧（hú）焊接（jiē）工藝無法達（dá）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 的第一字母的縮寫
Abbreviation for the first letter of Electric fusion welding
埋弧焊(SAW)-電熔焊（hàn）(EFW)的一種，就是通過一個（gè）或幾個自耗電極與工（gōng）件之間對金屬加熱（rè）使（shǐ）金屬之間結合中的一種工藝，電弧使金屬和填充材料充（chōng）分融化（huà），不需要加壓（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.
熔化氣體保護焊（hàn）(GMAW)--電熔焊(EFW)的一種，這種（zhǒng）工藝與埋弧（hú）焊類似，但它的保護是（shì）來自（zì）於（yú）惰性氣體（tǐ），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---這也是埋弧焊的一種，帶有一條螺旋（xuán）焊縫。
Spiral welding - This is also a submerged arc welding with a spiral weld.
