蒸呢机市场价格稳中有升成交相对仍处低位蒸呢机在焊接时有哪些保护质量的措施蒸呢机市场价格稳中有升。目前国内主导城市：邯郸武安、天津、江阴、上海、乐从等区域价格分别运行在3880、3870、3830、3930、4050元左右。较上周同期 相比，华北市场邯郸涨20元，天津涨50元；华东及华南市场江阴、上海、乐从均持稳运行。在限产的影响下，北方市场价格相对南方略为强势，不过区域价差略 有收…

保证蒸呢机在焊接时的保障措施，主要有五个方面。保证了这五个方面，那么高效蒸呢机的质量也能得到保障了。首先就是人， 人的因素是施焊的控制重点。因此，在施焊前，应选择技术熟练、持有焊工证的焊工，进行必要的技术培训、交底。并不得随意更换，保证施焊该管道焊工人员相对稳定。

There are five main safeguard measures for guaranteed square pipe during welding. The quality of galvanized square tubes can also be guaranteed if these five aspects are guaranteed. First of all, the human factor is the key point of welding control. Therefore, before welding, we should select skilled welders with welding license, and carry out necessary technical training and submission. It should not be replaced at will to ensure the relative stability of welders. 

其二是焊材的控制，保证采购的是正规渠道的焊材，有质保书、合格证，符合工艺要求；焊条头回收控制严格，以保证流向、用量；焊材要严格按工艺烘烤，并一次发放不超过半天用量。

The second is the control of welding materials, to ensure that the purchase of regular channels of welding materials, quality assurance, certification, in line with the requirements of the process; tightly control the recovery of electrode head to ensure flow direction, dosage; welding materials should be strictly baked in accordance with the process, and once issued not more than half a day of dosage.

第三就是 焊机，焊机须保证性能可靠、符合工艺需要；焊机必须有检定合格的电流、电压表，以保证焊接工艺的正确实施。焊接电缆不能过长，较长时要调整焊接参数。

The third is the welding machine, which must ensure reliable performance and meet the needs of the process; the welding machine must have qualified current and voltage meters to ensure the correct implementation of the welding process. Welding cable should not be too long. Welding parameters should be adjusted for a long time.

第四是焊接工艺方法，保证镀锌管特殊操作方法的严格实施，焊接工艺进行焊前坡口检查，施焊工艺参数、操作手法控制，焊后外观质量检查，必要时增加焊后无损检测。控制焊接层次、每道口的焊材用量。

Fourthly, the welding process is to ensure the strict implementation of special operation methods for galvanized pipes. The groove inspection before welding, the control of welding process parameters and operation methods, the appearance quality inspection after welding, and the non-destructive inspection after welding should be added when necessary. Control welding level and welding material consumption per pass.

第五就是焊接环境控制，保证施焊时的温度、湿度、风速符合工艺要求。

Fifth, the control of welding environment to ensure that the temperature, humidity and wind speed meet the requirements of welding process.
