在自動點焊機的焊接過程中,普遍存在的問題是:焊點在焊接過程中不能熔透而產(chǎn)生飛濺,導致點焊機的焊接質量不佳,因此在實際應用中應注意:
In the welding process of automatic spot welding machines, a common problem is that the welding points cannot melt thoroughly and produce splashes, resulting in poor welding quality. Therefore, in practical applications, attention should be paid to:
一、焊接點沒有穿透,熔核沒有形成或形成不好的形成。
1、 The welding point did not penetrate, and the fusion nucleus did not form or formed poorly.
1、無滲漏,即點焊時,無“豆狀”熔核排列。這個缺陷是很危險的,它會極大地改變焊接強度。
1. No leakage, that is, during spot welding, there is no "bean shaped" arrangement of molten nuclei. This defect is very dangerous as it will greatly alter the welding strength.
2、對焊接參數(shù)進行調試。若校驗確認參數(shù)無問題,則需檢查主電源電路,如:電源是否充足,是否損壞焊接變壓器等。
2. Debug welding parameters. If the calibration confirms that the parameters are correct, it is necessary to check the main power circuit, such as whether the power supply is sufficient and whether the welding transformer is damaged.
二、自動點焊機數(shù)量過多。
2、 There are too many automatic spot welding machines.
1、檢查支架與機體的絕緣電阻是否不良,是否形成局部短路。
1. Check if the insulation resistance between the bracket and the body is poor and if there is a local short circuit.
2、檢查觸點表面,如銅的撓性接縫,是否被嚴重氧化,觸點電阻的形成,會加重發(fā)熱。
2. Check if the contact surface, such as the flexible joints of copper, is severely oxidized, and the formation of contact resistance can exacerbate heating.
3、檢查焊縫的厚度及負載的連續(xù)性是否符合要求,焊機是否過熱。
3. Check whether the thickness of the weld seam and the continuity of the load meet the requirements, and whether the welding machine is overheating.
4、檢查進水壓力、水量和供水溫度是否適當,系統(tǒng)是否被污物所隔開,這些污物會由于冷卻不佳而導致電臂過熱。
4. Check whether the inlet pressure, water volume, and water supply temperature are appropriate, and whether the system is separated by dirt, which can cause overheating of the electric arm due to poor cooling.
三、焊接時產(chǎn)生的意外飛濺。
3、 Unexpected spatter generated during welding.
1、檢查電流是否過大或過低的壓力。
1. Check if the current is too high or the pressure is too low.
2、焊接工件的強度不足:焊接電流越來越小,而且焊接現(xiàn)象也不強。
2. The strength of the welded workpiece is insufficient: the welding current is decreasing, and the welding phenomenon is also not strong.
