Abstract

The utility model discloses a welding rod with a super-length gripping end. A layer of coating is coated at the outside of a welding core thereof, and the welding core is connected with the super-length gripper end of a section of low carbon steel. For a welding rod of steel alloys, a section of naked welding core with equal diameter is arranged between the gripper end and the welding core with the coating.

Description

Welding electrode with superlength gripping end

The utility model belongs to the Metal Material Welding welding rod, relates to a kind of improvement of welding bar for hand electric arc-welding, and the characteristics of this welding rod are bare terminal end length, claims no coating core wire again, and exposed length far surpasses existing bare terminal length.

Existing welding rod is when carrying out manual electric welding or built-up welding to the locations deep of parts mesopore; when the welding rod arcing is stopped arc to making soldering turret arrive the upper end open place in hole because of soldering turret can not enter to cause in the hole; though perhaps soldering turret can also reach and continue welding in the hole; but soldering turret also can have to stop arc because of block vision after arriving certain depth; no matter whether be clamped in welding rod residual length in the soldering turret like this near bare terminal end length; all being dropped need not; particularly for the welding rod of high-alloy steel and medium alloy steel; and copper; nickel; cobalt and alloy electrode thereof can cause very big waste.

The purpose of this utility model will provide a kind of welding rod with overlength bare terminal end, and the soldering turret clamping is thereon away from the arcing end, until the burning-out welding rod the coating part arranged, all do not hinder the carrying out of welding operation.

The purpose of this utility model is achieved in that the factory length of prolongation or spreading bare terminal, produces the welding rod with overlength bare terminal end.For the low-carbon steel core welding rod that is transition from coating of the middle and high content alloy element in the welding or the deposited metal of built-up welding, then prolong the bare terminal end of no coating, and for the most of of the alloying element of the middle and high content in the welding or the deposited metal of built-up welding or all be welding rod and copper, nickel, cobalt and the alloy electrode thereof of transition from core wire, then use one section naked core wire of isodiametric mild steel or ingot iron, cast iron and the naked core wire of other non-steel alloys with the bare terminal end spreading.

The accompanying drawing that the utility model adopts is as follows:

Fig. 1 is the welding rod that prolongs bare terminal end with low carbon steel welding core

Fig. 2 is the welding rod with cheap naked core wire spreading bare terminal ends such as low carbon steel welding core or ingot irons.

Give explanation below in conjunction with drawings and Examples:

As shown in Figure 1, welding rod is made up of low carbon steel welding core 1 that comprises bare terminal end and coating 2.Bare terminal end length all is no more than 30mm by the existing standard maximum, and for overcoming aforesaid drawbacks, the utility model embodiment is extended for 50～250mm with it.

Fig. 2 is the steel alloy welding rod schematic diagram with overlength bare terminal end, the outer bread of core wire (1) is with coating (2), there is the naked core wire (1) of one section no coating (2) centre, locate to connect the bare terminal end (3) of one section overlength at contact (4), bare terminal end (3) is made with low-carbon steel material, but also can use ingot iron or cheap material to make.

Compared with prior art, the welding rod that has an overlength bare terminal end has following advantages:

The welding rod of remnants can take full advantage of when 1, welding, and cuts the waste.

2, help welding, increase work efficiency at darker position.

Claims

1, a kind of welding rod with overlength bare terminal end, naked core wire (1) bag that it is characterized in that welding rod is with coating (2), and the length of its bare terminal end extends to 50～250 millimeters.

2, welding rod according to claim 1 is characterized in that its bare terminal end is low charcoal steel.

3, welding rod according to claim 1 is characterized in that the welding rod for high-alloy steel, and naked core wire (1) connects the low charcoal steel bare terminal end (3) of one section overlength in addition, and naked core wire (1) and bare terminal end (3) are located to join at tie point (4).
