1. Welding gap

焊接空隙也叫對(duì)口空隙，是焊接件對(duì)口處兩個(gè)焊件中間的空隙。焊接空隙直接關(guān)系焊口質(zhì)量。

Welding gap is also called butt gap, which is the gap between two weldments at butt joint of weldment. The welding gap is directly related to the quality of welded joint.

焊接空隙過(guò)小時(shí)焊縫不易焊透；焊接空隙過(guò)大時(shí)增加焊接的難度，填充量大影響焊接進(jìn)度，增大焊接應(yīng)力，易于發(fā)生焊接變型。

When the welding gap is too small, the weld is not easy to be penetrated; when the welding gap is too large, the welding difficulty is increased, the filling amount is large, the welding progress is affected, the welding stress is increased, and the welding deformation is easy to occur.

2、鈍邊尺寸

2. Blunt edge size

鈍邊尺寸也叫坡口尺寸，針對(duì)U形坡口還包括圓弧R的尺寸。

Blunt edge size is also called groove size. For U-shaped groove, it also includes the size of arc R.

鈍邊過(guò)大或過(guò)小都是會(huì)針對(duì)焊接質(zhì)量造成影響，鈍邊過(guò)小易于造成燒穿，鈍邊過(guò)大易于造成未焊透。假如接頭兩側(cè)的鈍邊同時(shí)過(guò)大或過(guò)小還相對(duì)易于處理，可以根據(jù)調(diào)節(jié)電流來(lái)控制熔深。假如由于一側(cè)鈍邊大，另一側(cè)鈍邊小，假如采用小電流，便會(huì)未焊透。假如采用大電流，便會(huì)燒穿，因而，這種情況特別在單面焊雙面成型的焊接工作中應(yīng)引起足夠的重視。

Too large or too small blunt edge will affect the welding quality, too small blunt edge is easy to cause burn through, too large blunt edge is easy to cause incomplete penetration. If the blunted edges on both sides of the joint are too large or too small at the same time and relatively easy to handle, the penetration can be controlled by adjusting the current. If because one side blunt edge is big, another side blunt edge is small, if use small current, can not weld thoroughly. If large current is used, it will burn through. Therefore, this situation should be paid enough attention to especially in the welding work of single side welding and double side forming.

U形坡口是一類節(jié)約焊材的坡口形式，可是圓弧R的尺寸務(wù)必保正焊條或焊絲可以易于地伸到坡口底部進(jìn)行焊接。

U-shaped groove is a kind of groove form which can save welding materials, but the size of arc r must be right, and the welding rod or welding wire can easily extend to the bottom of groove for welding.
