How does a welder work? Always be in a mask ...

Put on a welding mask for starters in order to look at the world through the eyes of a welder. Zero visibility, hostile darkness, through the smoke of soot of poisonous high-temperature fumes interrupted by the flickering local point of the electric arc and molten metal. Through the impenetrable window of the welding glass, the blinding blue-white electric arc is seen only as a yellowish star, and the molten, bubbling bright scarlet metal is seen as faint reddish water.

Looking at all this beauty, the welder, skillfully wielding an electrode, controls the flow of molten metal, directing it along the desired trajectory. When burning, the electrode is shortened on the eyes, therefore simultaneously with the manipulations of conducting along the seam it should be evenly brought closer to the epicenter of welding as it burns. If you miss it, it will spit with a spray and go out, leaving a nasty porous bubble on the seam. Too close - the arc will choke and the electrode will stick to the seam.

As long as the electrode does not burn out or the seam does not end, the welder will not stop. Neither splashes of molten metal in the sleeves, in the trousers and by the collar, nor the shouts of colleagues and even bosses, nor the eerie industrial crash and blows of a jackhammer over the ear - nothing will return the welder to the familiar world. The welder at this moment lives in his reality, limited by the view of the small black and green rectangle of the glass reticle.

Electrodes - steel rods, covered with a special dry coating, like Bengal lights. In childhood, living next to a construction site, we collected spilled electrodes on it, made a fire and put them into the fire, waiting in vain for the very shkvarchasche-blinding-sparkling flame that welders had carved at their workplace. How could we know that this requires an electric arc with its temperature - 6000 degrees Celsius.

At the melting point of the metal, all that is possible will fade and evaporate. Chemical components of electrode coating, metal vapor, scale, primers, paintwork and zinc coating ... All this terrible composition is inhaled by the welder directly and carefully controlling the melting epicenter at a very close distance. And when he hears about the dangers of passive smoking, he can condescendingly and mockingly say: "I would care about you."

Since the welding is electric, it is quite natural for the welder to communicate directly with volts and amperes. This is expressed in periodic electric shocks if the shoes and welder's boots suddenly become wet. The wetter the stronger. Standing on wet ground in wet boots and changing the electrode once again instead of burnt, unforgettable enchanting electrical sensations are guaranteed. “Name! Name! “K-k-krotov, your mother ...”

While the cook cooks the soup, the welder cooks the metal. The cook cooks soup in the kitchen, standing at the stove, stirring it with a spoon, inhaling an appetizing flavor; welder, breathing poisonous thick welding fumes, boils metal standing, sitting, lying, hanging above the ground, hunched up in a meter pipe, in a dusty smoky noisy workshop, on a rainy dirty construction site, in a clay trench, on the edge of a skyscraper wall, in a wet basement, in the melting-stuffy boiler room, in the frosty wind of the dock of the port ...

Pipelines, bridges, ships, cranes, trains, trucks, excavators, tanks ... Supporting frameworks of modern buildings, high-voltage electricity transmission masts, oil rigs ... Their metal forever stores, as a seal of the creator, a trace of the necessary hard work and life-giving, connecting electric arc heat, nested here Man in Mask.
