Operating Skills of Fired Surface of Stone Crafts

First, tool modification.It is better to use the welding gun type 6 or 12 for the stone burning process. The short welding point of the gun rod is about 80-100cm long.Gun mouth must use 6 types of welding torch spear plum flower mouth, and then welded into the card spear is used to burn straight welded into a diagonal plane type 】 【 edge, or 30 type cutting mouth can [is welded into a diagonal plane], but the latter this gun mouth fire big bad control fall off easily, gun nozzle on the side of card board when the fire heart inward, the burning method called card gun.There is also a fire core very long type 6 welding nozzle [not welding can also be] used to burn carved, such as this gun nozzle in the burning is the fire core directly against the surface of the fire, the operation is very difficult, very skilled, this method is called hanging gun.

Second, control of the heat.The oxygen decompression table should be set below 0.6, and the liquefied gas should be reduced as far as possible. This is based on personal work experience and feeling, and it is not absolute. Some people may be very skilled and have too much fire power, but they will not collapse or lose corners.Burning stone technology is the most taboo with a large number of air gun, generally with 6, 12, 20 welding gun.A lot of the fire workers are just making up the number, casually take a shorter large number (type 40, non-professionals can't see!).Then hang a common burning board gun mouth blow their own technology is how fierce, no modification of tools is not able to burn the effect of my picture!

Third, the operation of the card gun.The characteristic of gun mouth is: plum blossom mouth feather fast.Operation points are: the nozzle and board Angle Angle as large as possible to pull fast, the main point of this burning method is X, a common point is the principle of scissors, the wider the gun cut burn to the side, pull the more straight stay the wider.Two feet should be able to evenly forward and backward, it is funny that many fire workers will only back, only burn the right side, the work efficiency is very low, because their movements are not coordinated and lack of work experience.

Fourthly, operation of hanging gun.The characteristics of gun nozzle are: thin, long.This requires very skilled movements, a bit like writing brush, lifting, pressing, skimming and turning back.Operation points are: two feet to be stationary, by the body and hands to move evenly, and the operation method of the gun is just the opposite, many workers can not find out the points.

Fifth, comprehensive application.The most important stone burning process will have a selective use of tools!Burn curved straight edge with a card gun, burn carved or bad card with a hanging gun, large surface with a burning board of the big gun, only in this way can get twice the result with half the effort, improve work efficiency.The ancients cloud: ruler has short, inch has strong!With a bit longer gun burn along the wood than with a short gun effect is much better, so burning stone technology does not have to use a short gun!People in the field all know that only refit gun nozzle is the real skill, is also the core technology!

Sixth, burning stone technology to be bold and careful.As a result of burning stone technology, fire small often appear fire extinguishing, sticky fire excrement blocked gun nozzle and frequent backfire, the danger is very big.A lot of workers are afraid of tempering do not dare to learn to burn stone technology, so meet tempering to turn off the gun in time.If really back too fast or for a moment did not react, it is too late to turn off the fire, should immediately throw the welding gun to no one's place, quickly go to the first close the gas valve of the liquefied gas cylinder cut off the fire source, then close the oxygen gas cylinder of the gas valve.
