1.挤出焊接

1. Extrusion welding

挤出焊接这种方法是在制作设计的初期作出，这种焊接方法对制作描绘具有非常重要的作用。采用不同的焊接方法，所具有的焊接特点也是不一样的。

The extrusion welding method is made in the early stages of production design, and this welding method plays a very important role in the production description. The welding characteristics vary with different welding methods.

2.热板焊接

2. Hot plate welding

热板焊接使用的是电加热金属模具，使连接的塑料制件的表面软化的热塑性焊接。这种方法使用各种大小的热塑性制件。

Hot plate welding uses electrically heated metal molds to soften the surface of the connected plastic parts through thermoplastic welding. This method uses thermoplastic parts of various sizes.

3.热气焊接

3. Hot gas welding

热气焊接广泛的应用彩钢复合板产出制件所用的一种焊接方法，需要使用与被焊接制件相同的聚合物生产的焊条。

Hot gas welding is widely used in the production of color steel composite panels. It is a welding method that requires the use of welding rods produced by the same polymer brand as the welded parts.

彩钢复合板的搭接方式

Lapping method of color steel composite panels

1.自然搭接式

1. Natural overlap type

板型接缝的特点就是从水泥石棉波形瓦的形式延续而来，不过这种传统的扣合方法少要搭接一个半的波距。彩钢瓦在安装的时候，波距比较大，如果用作屋面的话，搭接一个半波，会大大地提高制作的经济成本，所以不少采用搭接一个波的做法，这种屋面板接缝在防水方面会存在一定的隐患。

The characteristic of plate type joints is that they are inherited from the form of cement asbestos corrugated tiles, but this traditional fastening method requires at least one and a half wave lengths to be overlapped. When installing color steel tiles, the wave distance is relatively large. If used as a roof, overlapping one and a half waves will greatly increase the economic cost of production. Therefore, many people use the method of overlapping one wave. This type of roof panel joint will have certain hidden dangers in waterproofing.

2.防水空腔式

2. Waterproof cavity type

这种方式是在两个扣合边处会形成一个4mm左右的空腔，这种空腔上有两块钢板在附着的时候形成的毛细管路，同时空腔的水柱会对室内外的大气进行平衡，但是会造成雨水渗入室内的情况。这种搭接方式已经应用到新一代压型板的断面设计中，是一种非常经济有效的方法，目前选用这种方法做屋面的比较多。

This method forms a cavity of about 4mm at the two buckle edges, which has capillary pipes formed by two steel plates when attached. At the same time, the water column in the cavity balances the indoor and outdoor atmosphere, but it can cause rainwater to seep into the room. This overlapping method has been applied to the cross-sectional design of the new generation of profiled panels and is a very economical and effective method. Currently, this method is widely used for roofing.

3.咬口式

3. Bite type

咬口式的搭接方式有180°和360°两种，使用咬边机将板材的两边接边咬合在一起，

There are two types of lap joint methods, 180 ° and 360 °, using a biting machine to bite the edges of the board together,

180°咬边在拼接过后不会那么紧密，360°是一种非常紧密的咬合方式，与白铁工的手工咬边比较相似，具有一定气密性的作用。这种版型的防水性能非常地好，但是造价也比较高。

180 ° biting edge is not as tight after splicing, and 360 ° is a very tight biting method, which is similar to the manual biting edge of a white iron worker and has a certain degree of airtightness. This type of version has excellent waterproof performance, but the cost is also relatively high.

4.扣盖式

4. Button cover type

扣盖式采用的是两百对称的设置，两边采用的是卡口构造，安装完毕之后扣上扣盖。这种是利用的空腔式的原理，但是扣板的使用量比较大。

The buckle style adopts a symmetrical setting of two hundred, with a bayonet structure on both sides. After installation, the buckle cover is fastened. This is based on the principle of using a cavity, but the use of buckle plates is relatively large.
