一、
焊条的保管和使用
Keep and use the electrode
1、焊条保管Electrode storage
1.1 各类焊条必须分类、分牌号堆放、避免混乱。
Various types of electrode must be classified, divided into grades piled up,avoid
confusion
1.2 焊条必须存放在较干燥的仓库内，建议室内温度在10ºC以上，相对湿度小于60%。
The
electrode must be stored in a dry warehouse, indoor temperature above the
recommended 10 º C, relative humidity is less than 60%
1.3 各类焊条储存时，必须离地面高30cm,离墙壁30cm以上存放，以免焊条受潮。
Various
types of electrode storage, must be high from the ground 30cm, away from the
wall above 30cm storage, in order to avoid electrode damp
1.4 焊条搬运、堆放过程中，要小心轻放，避免损伤药皮。焊条重叠堆放不要过高，以免压伤药皮。
When the electrode handling, stacking, should be handled with care to avoid
injury, electrode. Electrode overlapping stacking is not too high, in order to
avoid skin pressure.
2、焊条烘干Electrode drying
2.1 焊条存放时间过长时若受潮，但焊芯未生锈，药皮没有变质，焊条烘干后，可保持原来性能而不受影响使用。
Electrode
for a long time when wet, but the core not rust, coating is not bad, electrode
drying, can keep the original performance and is not influenced by the use of
各类型药皮的焊条烘干条件如下（参考值）The following welding rod drying conditions of various
types of coating (reference value)
酸性焊条acid electrode
烘烤温度150~~200ºC保温1h
Baking temperature of 150~~200 º C insulation 1H
碱性焊条basic electrode
烘烤温度350~~400ºC保温1h
Baking temperature of 350~~400 º C insulation 1H
纤维素焊条Cellulose electrode
烘烤温度80ºC保温1.5h~~2h
Baking temperature 80 º C insulation 1.5h~~2h
石墨型焊条Graphite electrode
烘烤温度200ºC保温1h
Baking temperature 200 º C insulation 1H
2.2 烘烤温度不可过高、过低。温度低了，水分除不掉；温度过高易造成药皮开裂、酥脆、脱落或药皮成分起变化，影响焊接质量。
Baking
temperature can not be too high, too low. Low temperature, water can't get rid
of; high temperature is easy to cause the drug skin cracking, crisp, shedding
or medicine skin composition change, affecting the quality of welding.
2.3 烘干后的碱性焊条，在室外漏放时间不宜超过4h。
Basic
electrode after drying, the outdoor drain time should not exceed 4h.
2.4 焊条重复烘干次数不可过多，否则易造成药皮脱落。
Electrode
repeated drying times can not be too much, otherwise easy to cause the coating
shedding
3、焊条报废Electrode scrap
3.1
焊条拆包后，若发现焊条药皮成块脱落或去掉药皮焊芯才有整块的锈斑，焊接后出现气孔、裂纹等缺陷，焊条应当报废。
Welding rod bag, if it is found that the
electrode piece off or remove coating electrode is piece of rust, welding
defects, cracks and other holes, electrodes shall be scrapped.
3.2
各类焊条如出现严重变质，如药皮霉变、脱落，药皮严重开裂，药皮严重搭结等，焊条应当报废。
Various types of electrode such as serious
deterioration, such as drug skin moldy, shedding, medicine skin cracking,
medicine skin serious bonding, welding shall be scrapped.
二、 焊丝的保管和使用Keep and use the solder wire
1、焊丝的保管 solder wire storage
1.1 焊丝应放于专用焊接材料库保管，注意库房通风、干燥，室温在10ºC ~40ºC之间,空气相对湿度应控制在60%以下，码放时离地面和墙壁保持30cm的距离。
The solder wire should be placed in a special
welding material warehouse storage warehouse, pay attention to ventilation,
drying, room temperature between 10 ºC ~40 º C , air relative humidity should
be controlled below 60%, the workpiece from the ground and walls to keep 30cm
distance
1.2
分清型号和规格存放,不能混放。
Distinguish the types and specifications of
storage, can not be mixed together
1.3
搬运过程要避免乱扔乱放，防止包装破损。一旦包装破损，可能会引起焊丝吸潮、生锈。
Transport process to avoid lying, packaging to
prevent breakage. Once the package is damaged, may cause wire absorption of
moisture, rust.
2、焊丝的使用The use of solder wire
2.1 开包后的焊丝应在2天内用完。
After opening the solder wire shall be finished
within 2 days
2.2
开包后的焊丝要防止其表面被冷凝结露，或被锈、油脂及其他碳氢化合物所污染，保持焊丝表面干净、干燥。
After opening the solder wire to prevent the
surface dew condensation, pollution or rust, grease and other hydrocarbons,
keep the wire surface clean, dry
2.3 一般情况下，药芯焊丝无需烘干，开封后应尽快用完。当焊丝没用完，需放在送丝机内过夜时，要用帆布、塑料布或其他物品将送丝机（或焊丝盘）罩住。以减少与空气中的湿气接触。
In general, flux-cored wire without drying,
Kaifeng should run out as soon as possible. When the wire did not run out, need
to be placed in the night feeding machine, with canvas, plastic cloth or other
items will wire feeding machine (or wire wheel covers). In order to reduce the
moisture in the air in contact with.
2.4
对于3天以上时间不用的焊丝，要从送丝机内取下。放回原包装内，封口密封，然后再存入具有良好保管条件的仓库中。
For more than 3 days without wires, to withdraw
from the wire feeding machine. Back to the original packaging, sealing, and
then deposited with good conditions of storage warehouse
三、焊剂的保管和使用Storage and use of weldingflux
1、 焊剂应存放在干燥的库房中，防止受潮影响焊接质量。应妥善运输、搬运焊剂，防止包装破损。
Weldingflux should be stored in dry warehouse,
prevent moisture affects the quality of welding. Should be properly transport
flux, handling, packaging to prevent breakage.
2、 使用前，焊剂应按说明书所规定的参数进行烘焙，熔炼焊剂一般在250~~300ºC烘焙2h，烧结焊剂通常在300~~400ºC烘焙2h。干燥时，焊剂散布在盘中，厚度最大不超过5cm.
Before use, parameter weldingflux should be
prescribed specifications for baking, roasting smelting flux general 2H at
250~~300 º C, sintered flux usually baked 2h in 300~~400 º C. When dry, the weldingflux
distribution in the plate, the maximum thickness of not more than 5cm.
3、 焊前，焊接处应清除铁锈、油污、水分等杂质。
Before welding, welding should be impurities to
remove rust, oil, water and so
4、 使用回收的焊剂，应清除掉里面的渣壳、碎粉及其它杂物，与新焊剂混匀后使用。
The use of recycled flux, slag, powder and
other should shell debris removed inside, after use with the new flux and
mixing.
5、 使用直流电源时，一般均采用直流反接，即焊丝接正极。
The DC power source is used, generally using DCEN,
namely the wire is connected to the positive electrode.
6、 焊剂再烘干，随着焊剂碱度和用途等不同，焊剂的再烘干温度也不一样。另外，焊接重要的高强度钢结构时，烘干后的焊剂要放入保温箱中存放，温度在120~~150ºC，随用随取，并限制使用的时间（通常为4h）,超过规定时间的焊剂，需再次烘干之后使用。
Flux drying, with flux basicity and the use of
different, flux drying temperature is not the same. In addition, the welding of
high strength steel structure is important, the dried flux is put into the
incubator storage, temperature of 120~~150 º C, with the use with the check,
and the restriction of the use of time (usually 4h), more than the prescribed
time flux, need to use again after drying.
