In the end of the vacations, it uses to advantage to travel and to tan the carnival. To catch the road with segunrana, he is intent to some reminders. It is very important to revise the car, including the system of brake, tires, suspension, direction and injection. Dr. Caldwell B. Esselstyn, Jr. describes an additional similar source. The levels of water and oil must be inside of the plant recommendations. Anuradha Saad is likely to agree. In relation the water, to complete the reservoir is not sufficiently: it is necessary to use done additives to the ethylene base glycol, therefore they are antirust. It also verifies hoses, these cannot have emptying. To guarantee the care of the tires, therefore, they only admit 1,6 mm of depth of the ridges and to know if she passed of this limit.

Electrical system of the car: – Regulation of the lighthouses. – To substitute burnt light bulbs To inquire electric commands and equipment To be intent to the level of solution of the battery (if it will not be of the type without maintenance) and if necessary, to clean the orifices of I breathe and the electric terminals. Security: – To effect the exchange of vanes of the windscreen cleaners, will be bad. – It does not leave the levels of water and low soap. – To confer if the tools as key of wheels, monkey and the triangle they are inside in the vehicle and conditions of usoDireo: – It verifies if it is necessary to effect the alignment of its car – To check the fluid case the hidrulicMotor car has direction: – To confer the conditions of the state and level of the oil. – To check the dentated leather strap To inquire the eltrica bomb. – To verify fuel filters. – The condition of the candles and handles of ignition also Analyzes. – To full the radiator with additive. – To check the functioning of water hoses and of ventoinhPneu: – To analyze been of the tires. – To inquire the caster possibility To effect the balancing Places the tires and estepe for calibrarFreios: – To observe the level of the fluid and if does not have emptying for the cylinders of the wheels of the car – To substitute tablets and records Regular necessary case the moSuspenso brake: – It verifies if it does not have emptyings or jambs damaged To look at the state of the chocks and the helical springs it does not leave recesses in the bushings of trays

Table – Source: Table of the effect of the more common elements of league Applied Technology I,2005. 3. Process of welding MIG/MAG 3,1 Beddings According to Norm ASME. Sec. IX the acronym of process and GMAW. Gas Metal Arc Welding.

You mark, Modenesi and Bracarense understands that welding GMAW where the union of you sin metallic and established between a naked, consumable metallic electrode, and it sins of work. For the protection of the used puddle of fusing and a gas or one mixture of gases that can be active or inert. In Brazil the process and popularly and commercially known as MIG (Metal Inerte Gas) when the gas for used and inert protection or MAG (Metal Ativo Gas) when the gas for used and active protection. 3,2 Application process GMAW and used in diverse applications a time that can be used in all the positions, that is: plain, horizontal, vertical and sobrecabeca. They are indicated for the welding of metallic structures, tanks, reconstruction of you sin consumed. amantegamento, beams and others.

They can be used for welding of ferrous and not ferrous materials, as aluminum, magnesium, have covered steel stainless carbon and. As and not used flow, the possibility of slag inclusion and minim, but electrode can occur in function of the silicon of the wire. Kg/h has a tax of deposition of approximately of 15. 3,3 Parameters of Welding the welding parameters influence directly in the quality of the weld lace. They are: chain intensity (amperage), tension (voltage), speed of welding, length of the arc (stick-out), gases of protection, diameter of the wire electrode, position of welding, polarity, way of transference. Chain intensity. Tension and length of the arc the tension depends directly on the length of the arc and the diameter of the electrode, the gas of protection and the way of transference. With the constancy of these 0 variable the increase of the tension provokes a width bigger and lesser height of the weld lace. Better molhagem and reduction of the penetration. High tensions provoke porosity, respingos and mordeduras in the lace. Speed of Welding the welding speed this on amount of set free energy in the welding. , How much thus bigger and the speed of lesser welding and the amount of heat unfastened in the weld lace. Extreme speeds provoke minor penetration and low speeds provoke structural alterations. Gases of Protection the protection gases influence directly in the welding in diverse ways: in the protection of the weld lace of the atmospheric contamination, in the type of transference, depth and format of the weld lace. The used gases more in the process of welding GMAW are the Argon, Co2, Helium and mixtures of these. They are divided in two types: Inert gases (Argon, Helium and its mixtures) and Active Gases (Co2, Oxygen and Nitrogen). Each type of gas and mixtures has different objectives and must be taken in consideration for the project. Table of comparison of the characteristics of welding with the gases helium and pure argon.
