焊接設備的選用是制定焊接工藝的一項重要內容，涉及的因素很多，但應注意以下幾個方面的因素。

　　The selection of welding equipment is an important aspect of developing welding processes, involving many factors, but attention should be paid to the following aspects.

　　1.被焊結構的技術要求

　　1. Technical requirements for welded structures

　　被焊結構的技術要求包括被焊結構的材料特性、結構特點、尺寸、精度要求和結構的使用條件等。

　　The technical requirements for the welded structure include the material properties, structural characteristics, dimensions, accuracy requirements, and usage conditions of the structure.

　　如果焊接結構材料為普通低碳鋼，選用弧焊變壓器即可;如果焊接結構要求較高，并且要求低氫型焊條焊接，則要選用直流弧焊機。

　　If the welding structural material is ordinary low carbon steel, an arc welding transformer can be selected; If the welding structure requires high requirements and low hydrogen welding rods are needed, a DC arc welding machine should be selected.

　　如果是厚大件焊接，則可使用電渣焊機;如果是棒材對接，可選用冷壓焊機和電阻對焊機。對活性金屬或合金、耐熱合金和耐腐蝕合金，根據具體情況，可選用惰性氣體保護焊機、等離子弧焊機、電子束焊機等。

　　If it is welding thick and large parts, an electric slag welding machine can be used; If it is bar docking, cold press welding machine and resistance welding machine can be used. For active metals or alloys, heat-resistant alloys, and corrosion-resistant alloys, inert gas shielded welding machines, plasma arc welding machines, electron beam welding machines, etc. can be selected according to specific circumstances.

　　對于大批量結構形式和尺寸固定的焊接結構，可以選用專用焊機。

　　For welding structures with fixed structural forms and sizes in large quantities, specialized welding machines can be used.

　　2.實際使用情況

　　2. Actual usage situation

　　不同的焊接設備，可以焊接同一焊件，這就要根據實際使用情況，選擇較為合適的焊接設備。

　　Different welding equipment can weld the same workpiece, which requires selecting the most suitable welding equipment based on actual usage.

　　如在野外焊接時缺泛電源和氣源，則只能選擇柴(汽)油直流弧焊發電機等弧焊發電機作為焊接設備。

　　If there is a lack of power and gas sources during outdoor welding, only welding generators such as diesel (gasoline) oil DC arc welding generators can be selected as welding equipment.

　　對焊后不允許再加工或熱處理的焊件，應選用能量集中、不需添加填充金屬材料、熱影響區較少電子束焊機。

　　For welded parts that are not allowed to be reworked or heat-treated after welding, an electron beam welding machine with concentrated energy, no need to add filler metal materials, and less heat affected zone should be selected.

　　3.經濟效益

　　3. Economic benefits

　　焊接時，焊接設備的能源消耗是相當可觀的。選用焊接設備時，應考慮在滿足工藝要求的前提下，盡可能選用耗電少、功率因素高的焊接設備。

　　During welding, the energy consumption of welding equipment is quite considerable. When selecting welding equipment, it should be considered to choose welding equipment with low power consumption and high power factor as much as possible while meeting the process requirements.
