Problems solved by technology

At present, the contact surface of the seam welding electrode is mostly a single plane or arc surface. The thickness of the stainless steel mesh is only about 0.082mm. The tips on both sides of the cylindrical surface are easy to cause the mesh to break. It is also easy to cause the broken wire of the mesh piece, and the qualified rate of the broken point of the rolling welding bubble is low

Embodiment Construction

[0017] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0018] The invention provides a structure of an electrode used for seam welding between a titanium alloy plate and a stainless steel mesh such as figure 1 and figure 2 As shown, it includes a first disc body 1 and a second disc body 2 integrally formed with the first disc body 1. The diameter of the second disc body 2 is larger than that of the first disc body 1, which can ensure the seam welding shielding gas pipeline The first disc body 1 has a diameter of 70 mm and a thickness of 10-15 mm, th...

Abstract

The invention provides an electrode for roll welding between a titanium alloy plate and a stainless steel mesh. The electrode comprises a first disc body and a second disc body, wherein the first disc body and the second disc body are integrally molded; and the diameter of the second disc body is larger than the diameter of the first disc body, the two sides of the bottom of the second disc body are inclination faces, and two corners at the edge of the end of the second disc body are profile bevels. By means of the manufactured electrode, the probability of wire breakage of the mesh in the roll welding process can be effectively decreased, and the percent of pass of products is improved.

Description

technical field [0001] The invention relates to the field of satellite propulsion subsystems, in particular to an electrode for seam welding of a titanium alloy plate and a stainless steel mesh for a surface tension storage tank. Background technique [0002] Surface tension tanks are widely used in satellite propulsion subsystems and are one of the most important components in satellite propulsion systems. In a microgravity or low gravity environment, liquids and gases in the space environment are generally in a mixed state of gas and liquid. In order for the tank to deliver bubble-free propellant to the thrusters under microgravity conditions, the propellant must be managed. [0003] The surface tension storage tank is an all-metal welded structure, which is mainly composed of two parts: the outer shell and the inner management device. Among them, the internal management device is responsible for collecting and managing the liquid in a microgravity environment to ensure ...
