Fiber cloth.
Specifically, the cover 41 of the present embodiment is in horn-like, opening up setting comprising: bottom plate 411 and four side plates
412.Bottom plate 411 is rectangular slab；Four 412 phases of side plate enclose, and along the obliquely outward setting of the outer edge of bottom plate 411,
Each side plate 412 is combined and constitutes the opening of cover 41 far from the side of bottom plate 411, wherein the cover 41 is cut toward opening direction
Face flaring.Further, the length direction of bottom plate 411 is consistent along the direction that welding point extends.The cover 41 of the present embodiment is anti-
Iron contamination only is caused to base material in soldering stainless steel or non-ferrous metal, while being able to bear certain high arc temperature；Loudspeaker
The structure of shape makes big at its open end, and bottom is small, can be in open injection convenient for gas.
More preferably, the side plate 412 of corresponding 411 length direction of bottom plate of cover 41 is transparent equipped with being made of crystal glass
Form 4121, can be about 1100 DEG C of heat resisting temperature, connect with the welding being fastened in cover 41 by the transparent window 4121 observation
Head, protection of the cover 41 easy to adjustment in time to welding point in it.In actual use, transparent window 4121 can also have it
His high temperature high voltage resistant glass is constituted.
In other embodiments, bottom plate 411 can be with square, round or other polygonized structures, and side plate 412 is to be adapted to
In the bottom plate 411.
It is additionally provided with partition 413 in cover 41, partition 413 is parallel to the setting of bottom plate 411 and each side of partition 413 and four side plates
412 connections, so that sealing space is divided into two spaces by partition 413；Wherein, being covered on partition 413 has multiple intercommunicating pores
4131, netted in cloth hole, which is interconnected by multiple intercommunicating pore 4131.Partition 413, bottom plate 411 and each
Side plate 412 surrounds plenum chamber 414；It more preferably, is reference with Fig. 4 paper direction, partition 413 is located at 412 up and down direction of side plate
The position of bottom plate 411 is leaned at middle part or middle part.This is set in cover 41 in the netted partition 413 of cloth hole, can play and uniformly divide
Gas body, and alleviate and offset interference of the arc stream to protective gas, prevent turbulent flow；Meanwhile partition 413 also has protection
Bottom plate 411 is not easy to be soldered the effect of arc through.
More preferably, partition 413 is made of red copper material, and red copper fusing point is high, form factor is poor, can effectively prevent electric arc height
Partition 413 is wounded in temperature breakdown.
Snorkel 43 is also made of red copper material, is arranged on cover 41 and protrudes into plenum chamber 414, so that external
Inert gas is input in sealing space through snorkel 43.Due to the setting of partition 413, snorkel 43 and welding surface are located at not
In same two spaces, prevent the metal melt in welding process from blocking the opening of snorkel 43.
Further, snorkel 43 be in U-shape in a plane bending setting, and the U-shaped lay snorkel 43 between
Every being staggeredly distributed with multiple ventholes 431, each venthole 431 is arranged towards bottom plate 411, so that 431 court of multiple venthole
To 411 direction of bottom plate to gas, gas buffer can be guided to 414 space of plenum chamber and be played the work at elimination 414 dead angle of plenum chamber
With, meanwhile, reversed refraction also acts as the effect for preventing gas high current from flinging again after gas injection to 41 bottom wall of cover.
Snorkel 43U shape bending lay plane between partition 413 and bottom plate 411, and with partition 413 and bottom plate
411 are spaced and are arranged in parallel.Wherein, the distance between the plane of the bending of snorkel 43 laying and bottom plate 411 are less than itself and partition
The distance between 413, so that the venthole 431 of snorkel 43 is closer to bottom plate 411, the gas sent out through venthole 431 can
It is reflected at once through bottom plate 411, it is more uniform convenient for the gas in plenum chamber 414.
More preferably, refering to Fig. 9, two rows of ventholes 431 are laid in the axial bottom of snorkel 43, the axial bottom of snorkel 43 here
Portion refers to the direction towards bottom plate 411.It is symmetrical arranged on 431 vertical base plate of two rows venthole, 411 direction, and going out on a row
Stomata 431 and the venthole 431 of another row are interspersed in the axial direction of snorkel 43.Further, two rows of 431 edges of venthole
For the circumferential angle theta of snorkel 43 between 60 °~120 °, best angle is 90 °, so that the more uniform injection of gas is to bottom plate
411。
It should be noted that the present embodiment Center Vent tube 43 is arranged in plenum chamber 414 in two continuous U-bend songs,
In actual use, it can also be that a U-shaped structure or more than two continuous U-shaped structures are constituted.
The structure of partition 413 and snorkel 43 in the cover 41 of the present embodiment designs, and makes protective gas in cover 41
Inside more evenly sufficiently, weld seam protection effect is substantially improved, protection color reaches golden yellow or silvery white.
As shown in figure 4, the outer end that snorkel 43 stretches out cover 41 is connected with connector 45, which includes: joint body
451 and the protrusion 452 axially extending along joint body 451；Protrusion 452 is set to joint body 451 far from snorkel 43
One end, to outside setting air supply pipe connect, wherein the outer diameter of protrusion 452 less than joint body 451 outer diameter,
External air supply pipe is set easily to be socketed on connector 45.
Cover 41 is opening up always to be arranged to be fastened on the welding point directed downwardly of tank case 2, the bottom of bracket 44 and cover 41
Plate 411 is fixedly connected, and bracket 44, which is equipped with, adjusts support 444, it can be adjusted on 44 length direction of bracket by adjusting support 444
Position, wherein the adjusting support 444 by connector 7 with hang walking mechanism 5 connect.
