1、气焊气割时的不正常火焰气焊气割火焰的好坏,集中体现了焊炬和割炬的工作性能。本文就工作中常见的几种不正常火焰,分析其产生的原因并提出解决的办法。 (1)三种正常的火焰这里指的是焊炬火焰、割炬预热火焰和割炬切割火焰(也叫风线、快风)。正常时,焊炬火焰的内焰为圆锥形,割炬预热火焰为圆环形或由6个小圆锥形火焰组成的梅花形(指梅花形割嘴)。割炬的切割火焰呈两条基本平行的直线。如图1所示。 (2)不正常的焊炬火焰从形状上看,最常见的有三种:弯曲形、圆头形、扫帚形,如图2所示。产生的原因有
1, gas welding Gas cutting abnormal flame Gas welding gas cutting flame is good or bad, focused on the torch and cutting torch performance. This article on the work of several common flames, analyze the causes and propose solutions. (1) three kinds of normal flame Here refers to the torch flame, torch preheat the flame and torch cutting flame (also called the wind, fast wind). Normally, the inner flame of the torch flame is conical, the torch preheats the torus in a torus shape or a plum-shaped (finger-shaped torus) flame consisting of six small conical flames. Cutting torch cutting flame was two basically parallel lines. As shown in Figure 1. (2) abnormal torch flame From the shape point of view, there are three most common: curved, round-shaped, broom-shaped, as shown in Figure 2. There are reasons
