ERW管（guǎn）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（de）壓力焊接方式， 焊縫中沒有填充其他成分，靠高（gāo）頻電流的集膚效應和臨近效應， 使板邊瞬間加熱到焊接溫度，由擠壓輥擠壓形成鍛造組織的焊縫。 高（gāo）品質（zhì）的鋼管要求采用（yòng）焊縫線上或離線熱處理，使焊區組織細化， 優（yōu）質ERW焊管的焊縫可以達（dá）到與母材相同的韌性（xìng）水準，這是埋弧（hú）焊接（jiē）工藝無法（fǎ）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 的第一字母的（de）縮寫
Abbreviation for the first letter of Electric fusion welding
埋弧焊(SAW)-電（diàn）熔焊(EFW)的一種，就是通過一個（gè）或幾個自耗電極（jí）與工件之間對金屬加熱使金（jīn）屬之間結（jié）合中的一種（zhǒng）工藝，電弧使金屬和填充材料充分融化，不需要加壓，填充（chōng）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(GMAW)--電熔焊(EFW)的一種，這種工藝與埋弧焊類（lèi）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（hàn）---這也是埋弧焊的一種，帶有一條螺旋焊縫（féng）。
Spiral welding - This is also a submerged arc welding with a spiral weld.
