3為宜。用φ4mm的金屬焊條(需采用合理工藝)或在加熱的情況下用鑄鐵焊條焊補(bǔ)。為防止電焊部位焊后產(chǎn)生內(nèi)應(yīng)力或翹曲，每焊一段要用小錘從焊道兩側(cè)向中間輕輕敲打，同時趁焊道紅熱時，用鑿口錘敲打焊道，以消除焊渣。如果裂紋過長，須分段隔開焊補(bǔ)，一般以20-30 mm長度為宜，待距離焊道70 mm處冷卻到能用手觸摸時，再焊下一段。若裂紋過深，可采用多層堆焊的方法，切不可一次焊成。氣缸體上制有潤滑油道、冷卻水道，裝有氣缸等。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="鎮(zhèn)江氣缸的選型,氣缸體"
