    • Disclosed is a method for non-vacuum electron beam welding metallic materials by means of a vacuum electron beam gun and with the aid of process gas. According to the inventive method, at least one inert gas (11, 28) is used in addition to the process gas (33), said inert gas (11, 28) being used in different manners and compositions by means of an inert gas supply apparatus in the form of a nozzle configuration (2), which is arranged on the vacuum electron beam gun (1). According to the invention, a process gas (33) is used that contains helium and 40 to 80 percent by volume of nitrogen, with/without admixing hydrogen and/or oxygen, while the inert gas contains argon, helium, and optionally added oxygen and nitrogen. The inventive method and the inventive device allow for optimal process control and thus inexpensive and quality-responsive material processing.

    • As a rule, electron beam welding takes place in a vacuum. However, this means that the workpieces in question have to be placed in a vacuum chamber and have to be removed therefrom after welding. This is time-consuming and a serious limitation of a process the greatest advantage of which is the option of welding workpieces of large thicknesses. Therefore the idea is to guide the electron beam (2) to the workpiece via a hollow wire, said wire thereby acting as a prolongation of the vacuum chamber (4) down to workpiece. Thus, a workpiece need not be placed inside the vacuum chamber, thereby exploiting the potential of electron beam processing to a greater degree than previously possible, for example by means of electron beam welding.
    • 通常,电子束焊接在真空中进行。 然而,这意味着所讨论的工件必须放置在真空室中,并且在焊接之后必须将其去除。 这是一个耗时且严重限制的工艺,其最大的优点是可以选择焊接厚度大的工件。 因此,这个想法是通过中空线将电子束2引导到工件,所述线由此用作真空室4向下延伸到工件上。 因此,不需要将工件放置在真空室内,从而例如通过电子束焊接,比以前更大程度地利用电子束处理的电位。

    • A welding technique whereby the passivation of chromiun oxide is conducted simultaneously with welding to realize treatment in a short time and in its turn to improve the productivity. Specifically, a technique for welding a weld material, for example, a pipe of a ferritic stainless steel, which comprises: switching a back shielding gas at the time of ordinary welding from an argon gas (or a hydrogen gas/an argon gas) to an argon gas containing an oxidizing gas added at the time of formation of a passive chromium oxide film; presetting the welding temperature conditions at the time of formation of the passive chromium oxide film so as not to cause the inner surface of the pipe to be melted; and, in order to conduct soaking of the pipe welded between the welding condition for the ordinary welding and the welding condition for the formation of a passive chromium oxide film and to replace the gas at the time of the ordinary welding with the gas used at the time of the formation of a passive chromium oxide film, conducting rotation by at least one turn under the welding condition for the formation of a passive chromium oxide film, thus forming a passive chromium oxide film in a weld simultaneously with the welding.
    • 一种焊接技术,其中氧化铬的钝化与焊接同时进行,以在短时间内进行处理,并提高生产率。 具体地说,一种用于焊接焊接材料的技术,例如铁素体不锈钢管,其特征在于,它包括:将普通焊接时的背面保护气体从氩气(或氢气/氩气)切换到 在形成钝态氧化铬膜时含有氧化气体的氩气; 预置形成钝化氧化铬膜时的焊接温度条件,以使管内表面不熔化; 并且为了在通常焊接的焊接条件和用于形成钝化的氧化铬膜的焊接条件之间进行焊接的管道的均热,并且在普通焊接时用在 无源氧化铬膜的形成时间,在焊接条件下旋转至少一圈以形成钝化的氧化铬膜,从而在焊接中与焊接同时形成钝化的氧化铬膜。
