英文翻译 Technology of Submerged Arc Welding埋弧焊技术The welding variables for submerged arc welding are similar to the other arc welding processes，with several exceptions.The electrode size is related to the weld joint size and the current recommended for the particular joint.This must also be considered in determining the number of passes or beads for a particular joint.Welds for the same joint dimension can be made with many or few passes；this depends on the weld metal metallurgy desired.Multiple passes are expensive but usually deposit higher-quality weld metal.The polarity is established initially and is based on whether maximum penetration or maximum deposition rate is required.埋弧焊技术的焊接变量与其他弧焊工艺的相似。但也有几个例外。电极尺寸与焊缝尺寸以及推荐给特定接头用的电流大小有关。确定特定接头的焊道或焊珠数量时也要考虑电极的尺寸。焊接相同尺寸的接头时，焊道数量可多可少，取决于所需的焊接金属冶金。多焊道的成本更高，但通过会熔覆高质量的焊接金属。极性应在一开始就根据是否需要。
\ Long time no see，give me a hug.You're the same since we met last time.感觉我的翻译要比楼上的口语化一些
