每一款设备都有市场的需求才会存在，冷焊机与氩焊机同样如此；在薄板焊接与焊补行业，市场需求决定了选取哪种焊机；

一、氩弧焊

1、 氩弧焊只能焊1.0以上的焊丝，焊补的精确度不高；

2、氩弧焊的温度比较高，容易变色、变形；

3、氩弧焊焊疤大，对模具的损伤比较大；

4、氩弧焊焊补模具后一般都不能上机床加工所以只能手工处理、比如锉刀挫、油石油，焊疤

大后就浪费时间了；

5、氩弧焊焊后需要热处理，否则影响产品的使用寿命

二、冷焊机

1、冷焊机达到了激光焊的焊接、焊补精度；

2、冷焊机能准确地设定输出电流和焊补时间，不会变色、变形；

3、冷焊机焊疤小，对模具损伤小；

4、冷焊机焊补后可以上机床加工；

5、冷焊机焊后无需热处理，不会影响产品使用寿命。

There is a market demａnd for each piece of equipment. The same is true for cold welding machines and argon welding machines. In the thin plate welding and welding repair industry, market demａnd determines which welding machine to choose;

First, argon arc welding

1. TIG welding can only weld more than 1.0 wire, the accuracy of welding repair is not high;

2. The temperature of argon arc welding is relatively high, which is easy to discolor and deform;

3. Large argon arc welding scars cause large damage to the mold;

4. After argon arc welding and repairing the mold, it can not be processed on the machine tool, so it can only be handled manually, such as file cutting, oil and petroleum, welding scars.

Wasted time

5. After TIG welding, heat treatment is needed, otherwise it will affect the service life of the product.

Second, cold welding machine

1. The cold welding machine has achieved laser welding and welding repair accuracy;

2. The cold welding machine can accurately set the output current and welding repair time without discoloration or deformation;

3. Cold welding machine has less welding scars and less damage to the mold;

4. Cold welding machine can be machined after welding repair;

5. The cold welding machine does not require heat treatment after welding, and will not affect the service life of the product.
