Definitions

  • Arc welding is today the dominating method of joining metals.
  • machines for this purpose.
  • These machines are electrical apparatuses for generating the form of electrical energy best suited to each purpose.
  • Many of these apparatuses also have devices, in the form of a gas supply, for protecting the arc.
  • the literature refers to a number of proposed solutions for how to use a vehicle's electrical system to be able to perform arc welding.
  • the American publications 3,681 ,611, 4,853,557 and 4,868,480 can stated specially here.
  • This invention involves a method with, compared to the methods described in the literature, distinctive power, which implies that without major intervention or with a simple connecting device, can use a vehicle's standard equipment. With that it should be clear that this constitutes commercially favourable equipment with a great industrial potential.
  • the battery and the alternator in a 12 V (for which an extra battery must be used) or 24 V system, connected together with a rectifier (diode) to a welding electrode, it is possible to weld, if the work piece and alternator are earthed together with the negative terminal of the battery.
  • This arrangement provides a self- controlling welding system, as regards amperage, for ordinary electrode sizes.
  • a major simplification is achieved if a handle that contains a holder for an electrode is equipped with the necessary rectifier connected to the battery.
  • the decisive factor is that it must be possible to obtain the voltage to strike an arc, which is normally about 70 V, using the alternator, to then, with the normal battery voltage, perform welding with an amperage greater than the alternator's normal rated current.
  • another, independent source of direct current (17) can be used instead of the alternator.
  • An example is an alternator with rectification or an existing direct current source connected to the mains.
  • this new independent direct current source will be responsible for ensuring that the voltage necessary to strike an arc for the electrode is obtained.
  • another independent source of current (18) such as a battery, will provide the necessary current to permit welding.
  • One (18) provides low-voltage direct current (e.g. a battery) and the other (17) a high-voltage (in relation to the first source) direct current.
  • low-voltage direct current e.g. a battery
  • high-voltage direct current e.g. a high-voltage direct current
  • the mechanical connection between the engine and alternator shall be retained to ensure the engine's other essential functions (cooling, air conditioning, etc.). Disconnection may be achieved either by using normal hand tools to remove the terminal connections or by fitting a suitable connecting device.
  • the connecting device then permits disconnection between the alternator and the electrical system and makes the following additional connections.
  • a lead is connected between the work piece and the vehicle's chassis (3) or the battery's negative terminal (11).
  • To the battery's positive terminal (12) is connected by a cable (4) a device that consists of a rectifier (5) placed either in the vehicle or in a handle (6).
  • a cable is connected from the battery's positive terminal directly to the alternator's excitation winding (7).
  • a lead is required from alternator's positive terminal (9) to the lead downstream of the rectifier (8). After this connection, the alternator can no longer charge the battery (10).
  • the battery's positive terminal (12) is, however, still connected to the vehicle's electrical system.
  • the connecting device mentioned above need not necessarily be used but it does provide great practical advantages. It will be specially advantageous if the connecting device is used for simplification as described above and is combined with the rectifier being placed in a handle, which is at the same time the attachment device for the welding electrode. This provides a very simple device that permits practical and fast use of the device.
  • Figure 2 indicates the appearance of the connecting device.
  • This device can now be placed in the cab of the vehicle, for example. It is also possible to place the device under the bonnet or on the outside of the vehicle, to simplify the switchover.
  • the connecting device is best described in detail as follows: Using a connecting device with several connecting functions, the following functions can be effected.
  • the battery's positive terminal (12) is connected on activation to the weld electrode holder via the rectifier (5).
  • the alternator's charging terminal (positive terminal) (9) is connected on activation to the weld electrode holder (6), but downstream of the rectifier (5).
  • the alternator's excitation winding (7) is connected directly to the battery's positive terminal (12). Other connections to the alternator (16) are disconnected from the system.
  • the handle can be designed as shown in Figure 3. It is then practical that the rectifier be placed in the handle.
  • the lead from the battery (4) and the lead from the alternator (17), which are in a joint cable are connected using a plug.
  • the engine may be started. Set the engine speed so that the voltage necessary to strike an arc is generated for the electrode against the work piece (V 0 ).
  • the voltage from the alternator drops, in accordance with the first part of the graph in Figure 4. to the battery's working voltage (VB).
  • the amperage from the alternator (I j ) then assumes a value, which is the alternator's rated current.
  • the arc's further energy demand in the form of current (I2 - I j ) at the battery's working voltage is supplied by the battery.
  • the possible welding time will be equal to the time the battery requires for recharging.
  • step with the battery discharging during the course of welding recharging will be required.
  • the electrode holder is attached to the pin (15), after which the alternator's energy is supplied to the battery in the form of a quick charge at the alternator's rated current.
  • the charging time will be equal to the effective welding time.
  • the handle cools as the rectifier (the diode) heats up during welding.

Abstract

La présente invention concerne, non seulement un procédé mettant en ÷uvre l'installation électrique standard d'un véhicule, laquelle installation permet de réaliser des soudures à l'arc, mais également un dispositif permettant le basculement entre le mode de fonctionnement normal du véhicule et le mode soudure, sans qu'il soit nécessaire de modifier l'installation standard. Le dispositif est constitué d'un porte-électrode (6) intégrant un redresseur (5) et un sélecteur multifonction (14) qui prend en charge en une seule opération l'ensemble des basculements nécessaires à la soudure. Une réalisation particulière met en ÷uvre deux sources indépendantes de courant, l'une pour du courant continu basse tension, l'autre, en relation avec la précédente, pour le courant continu haute tension. Le principe de l'invention est de faire coopérer les deux sources de courant de façon à permettre la soudure à l'arc.
